NVIDIA

The set of samples demonstrates how to interact with an external graphics API via Unigine API (ResourceExternalMemory and ResourceFence). Although the samples show interaction with CUDA, you may use them as the basis for integrating the Engine GAPI (Vulkan, DX11, DX12) with other GAPI (OpenGL, DX, CUDA, etc.) that can accept the handle and import a synchronization primitive (such as external semaphore in CUDA).

This approach may help in configuring interaction of various API using different GAPI, such as interaction of MediaFoundation using DX11 with the Engine using DX12 or Vulkan.

The samples also illustrate how to take the data directly from the video memory without CPU roundtrip and processing it using non-engine graphics API.

CUDAMeshDynamic#

Warning
The functionality described in this chapter is not available in the Community SDK edition.
You should upgrade to Sim SDK edition to use it.


Vertices of a shared dynamic mesh are processed on GPU using CUDA.

To build the sample, use CUDA Toolkit v12.3.

On Linux: after installing the CUDA Toolkit, make sure that the PATH environment variable includes /usr/local/cuda-12.2/bin.

CUDAStructuredBufferWrite#

Warning
The functionality described in this chapter is not available in the Community SDK edition.
You should upgrade to Sim SDK edition to use it.


Particles in a shared structured buffer are updated on GPU using CUDA, and rasterized manually using Unigine Material with Compute Shader.

To build the sample, use CUDA Toolkit v12.3.

On Linux: after installing the CUDA Toolkit, make sure that the PATH environment variable includes /usr/local/cuda-12.2/bin.

CUDATextureTransfer#

Warning
The functionality described in this chapter is not available in the Community SDK edition.
You should upgrade to Sim SDK edition to use it.


A shared texture is processed with CUDA and copied from video memory to RAM into Unigine Image.

To build the sample, use CUDA Toolkit v12.3.

On Linux: after installing the CUDA Toolkit, make sure that the PATH environment variable includes /usr/local/cuda-12.2/bin.

CUDATextureWrite#

Warning
The functionality described in this chapter is not available in the Community SDK edition.
You should upgrade to Sim SDK edition to use it.


A shared texture is processed with CUDA and displayed on the Unigine Object as a texture on a cube.

To build the sample, use CUDA Toolkit v12.3.

On Linux: after installing the CUDA Toolkit, make sure that the PATH environment variable includes /usr/local/cuda-12.2/bin.
