## <hr>Reorders triangles for better vertex cache locality.
#
# The step tries to improve the ACMR (average post-transform vertex cache
# miss ratio) for all meshes. The implementation runs in O(n) and is
# roughly based on the 'tipsify' algorithm (see <a href="
# http:www.cs.princeton.edugfxpubsSander_2007_%3ETRtipsy.pdf">this
# paper<a>).
#
# If you intend to render huge models in hardware, this step might
# be of interest to you. The <tt>#AI_CONFIG_PP_ICL_PTCACHE_SIZE<tt>config
# setting can be used to fine-tune the cache optimization.
#
aiProcess_ImproveCacheLocality = 0x800
## <hr>Searches for redundantunreferenced materials and removes them.
#
# This is especially useful in combination with the
# #aiProcess_PretransformVertices and #aiProcess_OptimizeMeshes flags.
# Both join small meshes with equal characteristics, but they can't do
# their work if two meshes have different materials. Because several
# material settings are lost during Assimp's import filters,
# (and because many exporters don't check for redundant materials), huge
# models often have materials which are are defined several times with
# exactly the same settings.
#
# Several material settings not contributing to the final appearance of
# a surface are ignored in all comparisons (e.g. the material name).
# So, if you're passing additional information through the
# content pipeline (probably using #magic# material names), don't
# specify this flag. Alternatively take a look at the
# <tt>#AI_CONFIG_PP_RRM_EXCLUDE_LIST<tt> setting.
#
aiProcess_RemoveRedundantMaterials = 0x1000
## <hr>This step tries to determine which meshes have normal vectors
# that are facing inwards and inverts them.
#
# The algorithm is simple but effective:
# the bounding box of all vertices + their normals is compared against
# the volume of the bounding box of all vertices without their normals.
# This works well for most objects, problems might occur with planar
# surfaces. However, the step tries to filter such cases.
# The step inverts all in-facing normals. Generally it is recommended
# to enable this step, although the result is not always correct.
#
aiProcess_FixInfacingNormals = 0x2000
## <hr>This step splits meshes with more than one primitive type in
# homogeneous sub-meshes.
#
# The step is executed after the triangulation step. After the step
# returns, just one bit is set in aiMesh::mPrimitiveTypes. This is
# especially useful for real-time rendering where point and line
# primitives are often ignored or rendered separately.
# You can use the <tt>#AI_CONFIG_PP_SBP_REMOVE<tt> option to specify which
# primitive types you need. This can be used to easily exclude
# lines and points, which are rarely used, from the import.
#
aiProcess_SortByPType = 0x8000
## <hr>This step searches all meshes for degenerate primitives and
# converts them to proper lines or points.
#
# A face is 'degenerate' if one or more of its points are identical.
# To have the degenerate stuff not only detected and collapsed but
# removed, try one of the following procedures:
# <br><b>1.<b> (if you support lines and points for rendering but don't
# want the degenerates)<br>
# <ul>
# <li>Specify the #aiProcess_FindDegenerates flag.
# <li>
# <li>Set the <tt>AI_CONFIG_PP_FD_REMOVE<tt> option to 1. This will
# cause the step to remove degenerate triangles from the import
# as soon as they're detected. They won't pass any further
# pipeline steps.
# <li>
# <ul>
# <br><b>2.<b>(if you don't support lines and points at all)<br>
# <ul>
# <li>Specify the #aiProcess_FindDegenerates flag.
# <li>
# <li>Specify the #aiProcess_SortByPType flag. This moves line and
# point primitives to separate meshes.
# <li>
# <li>Set the <tt>AI_CONFIG_PP_SBP_REMOVE<tt> option to
# @code aiPrimitiveType_POINTS | aiPrimitiveType_LINES
# @endcode to cause SortByPType to reject point
# and line meshes from the scene.
# <li>
# <ul>
# @note Degenerate polygons are not necessarily evil and that's why
# they're not removed by default. There are several file formats which
# don't support lines or points, and some exporters bypass the
# format specification and write them as degenerate triangles instead.
#
aiProcess_FindDegenerates = 0x10000
## <hr>This step searches all meshes for invalid data, such as zeroed
# normal vectors or invalid UV coords and removesfixes them. This is
# intended to get rid of some common exporter errors.
#
# This is especially useful for normals. If they are invalid, and
# the step recognizes this, they will be removed and can later
# be recomputed, i.e. by the #aiProcess_GenSmoothNormals flag.<br>
# The step will also remove meshes that are infinitely small and reduce
# animation tracks consisting of hundreds if redundant keys to a single
# key. The <tt>AI_CONFIG_PP_FID_ANIM_ACCURACY<tt> config property decides
# the accuracy of the check for duplicate animation tracks.
#
aiProcess_FindInvalidData = 0x20000
## <hr>This step converts non-UV mappings (such as spherical or
# cylindrical mapping) to proper texture coordinate channels.
#
# Most applications will support UV mapping only, so you will
# probably want to specify this step in every case. Note that Assimp is not
# always able to match the original mapping implementation of the
# 3D app which produced a model perfectly. It's always better to let the
# modelling app compute the UV channels - 3ds max, Maya, Blender,
# LightWave, and Modo do this for example.
#
# @note If this step is not requested, you'll need to process the
# <tt>#AI_MATKEY_MAPPING<tt> material property in order to display all assets
# properly.
#
aiProcess_GenUVCoords = 0x40000
## <hr>This step applies per-texture UV transformations and bakes
# them into stand-alone vtexture coordinate channels.
#
# UV transformations are specified per-texture - see the
# <tt>#AI_MATKEY_UVTRANSFORM<tt> material key for more information.
# This step processes all textures with
# transformed input UV coordinates and generates a new (pre-transformed) UV channel
# which replaces the old channel. Most applications won't support UV
# transformations, so you will probably want to specify this step.
#
# @note UV transformations are usually implemented in real-time apps by
# transforming texture coordinates at vertex shader stage with a 3x3
# (homogenous) transformation matrix.
#
aiProcess_TransformUVCoords = 0x80000
## <hr>This step searches for duplicate meshes and replaces them
# with references to the first mesh.
#
# This step takes a while, so don't use it if speed is a concern.
# Its main purpose is to workaround the fact that many export
# file formats don't support instanced meshes, so exporters need to
# duplicate meshes. This step removes the duplicates again. Please
# note that Assimp does not currently support per-node material
# assignment to meshes, which means that identical meshes with
# different materials are currently #not# joined, although this is
# planned for future versions.
#
aiProcess_FindInstances = 0x100000
## <hr>A postprocessing step to reduce the number of meshes.
#
# This will, in fact, reduce the number of draw calls.
#
# This is a very effective optimization and is recommended to be used
# together with #aiProcess_OptimizeGraph, if possible. The flag is fully
# compatible with both #aiProcess_SplitLargeMeshes and #aiProcess_SortByPType.
#
aiProcess_OptimizeMeshes = 0x200000
## <hr>A postprocessing step to optimize the scene hierarchy.
#
# Nodes without animations, bones, lights or cameras assigned are
# collapsed and joined.
#
# Node names can be lost during this step. If you use special 'tag nodes'
# to pass additional information through your content pipeline, use the
# <tt>#AI_CONFIG_PP_OG_EXCLUDE_LIST<tt> setting to specify a list of node
# names you want to be kept. Nodes matching one of the names in this list won't
# be touched or modified.
#
# Use this flag with caution. Most simple files will be collapsed to a
# single node, so complex hierarchies are usually completely lost. This is not
# useful for editor environments, but probably a very effective
# optimization if you just want to get the model data, convert it to your
# own format, and render it as fast as possible.
#
# This flag is designed to be used with #aiProcess_OptimizeMeshes for best
# results.
#
# @note 'Crappy' scenes with thousands of extremely small meshes packed
# in deeply nested nodes exist for almost all file formats.
# #aiProcess_OptimizeMeshes in combination with #aiProcess_OptimizeGraph
# usually fixes them all and makes them renderable.
#
aiProcess_OptimizeGraph = 0x400000
## <hr>This step flips all UV coordinates along the y-axis and adjusts
# material settings and bitangents accordingly.
#
# <b>Output UV coordinate system:<b>
# @code
# 0y|0y ---------- 1x|0y
# | |
# | |

# 0x|1y ---------- 1x|1y

#
# You'll probably want to consider this flag if you use Direct3D for
# rendering. The #aiProcess_ConvertToLeftHanded flag supersedes this
# setting and bundles all conversions typically required for D3D-based
# applications.
#
aiProcess_FlipUVs = 0x800000
## <hr>This step adjusts the output face winding order to be CW.
#
# The default face winding order is counter clockwise (CCW).
#
# <b>Output face order:<b>
# @code
# x2

# x1
# @endcode
#
aiProcess_FlipWindingOrder = 0x1000000
## <hr>This step splits meshes with many bones into sub-meshes so that each
# su-bmesh has fewer or as many bones as a given limit.
#
aiProcess_SplitByBoneCount = 0x2000000
## <hr>This step removes bones losslessly or according to some threshold.
#
# In some cases (i.e. formats that require it) exporters are forced to
# assign dummy bone weights to otherwise static meshes assigned to
# animated meshes. Full, weight-based skinning is expensive while
# animating nodes is extremely cheap, so this step is offered to clean up
# the data in that regard.
#
# Use <tt>#AI_CONFIG_PP_DB_THRESHOLD<tt> to control this.
# Use <tt>#AI_CONFIG_PP_DB_ALL_OR_NONE<tt> if you want bones removed if and
# only if all bones within the scene qualify for removal.

MomentFactory/Omniverse-Lidar-Live-Synthetic-Data/README.md | # MF Lidar live synthetic data [mf.ov.lidar_live_synth]
Adds an Action Graph Node ("Generic/Beam to Ouster UDP") to send Isaac beam data via the Ouster(tm) UDP procotol.
This allows any third party software implementing Ouster(tm) lidars to be connected to simulated sensors instead of physical sensors.
Developped for kit 105.1 and currently working only in Isaac Sim.
This extensions provides pre-built binaries for Windows and Linux x86_64.
You may want to compile from the [source code](https://github.com/MomentFactory/Omniverse-Lidar-Live-Synthetic-Data)
## Requirements
- kit 105 based
- Isaac Sim > 2023.1.0
- Linux or Windows platforms
### Supported Lidars
Currently, only Ouster™ sensors are supported.
The Lidar must have 16, 32, 64 or 128 rows to be supported by the procotol.
Lidar FOVs and resolutions are not transmitted in the protocol and therefore should match those of an actual Ouster(tm) model (22.5, 45 or 90 degrees FOV) for an accurate reconstruction by the receiving software.
JSON config files that describe the angles of the beams for an external application are included in the 'data' folder (example : [OusterJsonConfigOmniverse-OS0-16.json](source/extensions/mf.ov.lidar_live_synth/data/OusterJsonConfigOmniverse-OS0-16.json)). These files can be used in Cirrus as the Ouster(tm) Json Config file to properly recronstruct the data with the correct beam angles. OS0 are 90 degrees FOV, OS1 are 45 and OS2 are 22.5.
## Build
### Windows
- Run `./build.bat`
### Linux
- Install Docker
- Run `./build.sh`
## Using the extension
Requires Isaac Sim as well as a third party software that can receive and parse Ouster Lidar sensors frames.
You can use the [isaac_lidar_sample_moving_cube.usd](source/extensions/mf.ov.lidar_live_synth/samples/isaac_lidar_sample_moving_cube.usd), or [isaac_lidar_ouster_sample.usd](source/extensions/mf.ov.lidar_live_synth/samples//isaac_lidar_ouster_sample.usd), or create your own following the instructions below.
### Enable the extension
In Isaac Sim :
- Windows > Extensions.
- Switch to THIRD PARY tab.
- Install and enable the extension.
### In Isaac Sim:
1. Open or create a scene
- Meshes requires a Rigidbody to intercept Lidar raycast
- Right-click a mesh, then select `Add / Physics / Rigid Body`
2. Add a Lidar to the scene if not present
- `Create / Isaac / Sensors / Lidar / Generic`
- Unfold Raw USD Properties
- Check `drawPoints` and/or `drawLines` if you want to see the point cloud
- Check the `enabled` property
- Use `horizontalFov`, `horizontalResolution`. `maxRange`, `minRange`, `verticalFov`, and `verticalResolution` to define the Lidar raycast zone
- set `rotationRate` to `0` if you want continuous raycast
3. Create an action graph
- Right-click the Stage, then select `Create / Visual Scripting / Action Graph`
- Right-click the Action Graph then select "Open Graph"
- Add a `Event / On Playback Tick` node
- Add a `Isaac Range Sensor / Isaac Read Lidar Beam Node`
- Connect the "Tick" output to the "Exec In" input
- Add a `Generic / Beam to Ouster UDP` node
- Connect the "Exec Out" output to the "Exec In" input
- Connect the outputs of `Isaac Read Lidar Beam Node` to the matching `Beam to Ouster UDP` inputs
- `Azimuth Range`
- `Horizontal Resolution`
- `Linear Depth Data`
- `Num Cols`
- `Num Rows`
4. Press the play icon (SPACE) to begin the simulation
#### Beam to Ouster UDP fields
- `IP Address` (string): The IP address to send the data to.
- `Port` (int): The port to send the data to.
- `Broadcast` (bool): Check to indicate the IP Address is a broadcast address.
## Developer notes
As the extension is written in C++ for performance reasons, developers need to build it before using it. Most of it works in the same way as the official [Omniverse C++ examples](https://github.com/NVIDIA-Omniverse/kit-extension-template-cpp).
The first step is to run the `build.bat` file at the root of the repo. It will generate the actual extension files usable by Omniverse, as well as the Visual Studio files. It is recommended to work in Visual Studio (2019 and above) for C++, although VSCode should also work. The `build.bat` script generates the VS2019 `.sln` files in `_compiler\vs2019\kit-extension-template-cpp.sln` . It should work as-is. Do not upgrade the compiler and Windows SDK versions if asked to do so, and install the correct Windows SDK for the VS Installer if it is missing on your machine.
Unlike the samples, we do not recommend running the project by launching it via Visual Studio, since the extension is made specifically for Isaac Sim, and Visual Studio doesnt launch it within an Isaac Sim environment. It is recommended to run Isaac and attach the VS debugger to it by going to Debug -> Attach to Process and selecting the kit.exe coresponding to Isaac. Make sure to attach to Native Code. If you have the "Python - Profiling" extension, it might want to try to attach to Python code instead. One thing to note is that the symbols for the extension will only be loaded IF the extension is enabled after attaching. If the extension is already enabled, disabling then enabling it will also work. Also, to update the extension in Isaac after doing some changes and building, it needs to be disabled and enabled again (The extension willl probably fail to build if it is in use as the dll cannot be overwritten anyways).
To add the extension to Isaac, simply add the built plugin folder (`c:/git/omniverse/omniverse-lidar-synthetic-data/_build/windows-x86_64/release/exts` or `c:/git/omniverse/omniverse-lidar-synthetic-data/_build/windows-x86_64/debug/exts` for a debug build) to the extension manager paths.

MomentFactory/Omniverse-Lidar-Live-Synthetic-Data/source/extensions/mf.ov.lidar_live_synth/docs/README.md | # MF Lidar live synthetic data [mf.ov.lidar_live_synth]
Adds an Action Graph Node ("Generic/Beam to Ouster UDP") to send Isaac beam data via the Ouster(tm) UDP procotol.
This allows any third party software implementing Ouster(tm) lidars to be connected to simulated sensors instead of physical sensors.
Developped for kit 105.1 and currently working only in Isaac Sim.
This extensions provides pre-built binaries for Windows and Linux x86_64.
You may want to compile from the [source code](https://github.com/MomentFactory/Omniverse-Lidar-Live-Synthetic-Data) |
