(Demo) vkRtxInfo: VK_NV_ray_tracing Information




Vulkan RTX info with GeeXLab



I started the integration of NVIDIA ray tracing support in the Vulkan plugin of GeeXLab. The first concrete contact is the reading of VK_NV_ray_tracing properties for a particular Vulkan GPU.

This demo requires GeeXLab 0.27.7.1+.

Here are the properties for a GeForce RTX 2070 or a RTX 2080:

VK_NV_ray_tracing:
- shaderGroupHandleSize => 16
- maxRecursionDepth => 31
- maxShaderGroupStride => 4096
- shaderGroupBaseAlignment => 64
- maxGeometryCount => 16777215
- maxInstanceCount => 16777215
- maxTriangleCount => 536870911
- maxDescriptorSetAccelerationStructures => 1048576

Remark: this first demo is in… OpenGL. This demo only displays Vulkan related info via the Vulkan plugin and draws the scene content in OpenGL.
