torchdrivesim.rendering.nvdiffrast¶

Nvdiffrast-based renderers, equivalent to those based on PyTorch3D but sometimes faster. This module imports correctly if nvdiffrast is missing, but the renderer will raise the NvdiffrastNotFound exception.

Attributes¶

`is_available`
`logger`
`glctx_sessions`

Exceptions¶

NvdiffrastNotFound

Nvdiffrast is not installed.

Classes¶

`NvdiffrastRendererConfig`	Configuration of nvdiffrast-based renderer.
`NvdiffrastRenderer`	Similar to PyTorch3DRenderer, and producing indistinguishable images, but sometimes faster.

Functions¶

get_glctx_session(device[, opengl])
