chrono::sensor::ChVulkanRTDevice Class Reference
SENSOR module » Vulkan ray tracing backend

Description

Minimal RAII owner for Vulkan objects required by the Sensor RT backend.

This class deliberately owns only instance/device/queue state. Acceleration structures, descriptor sets, SBTs, and command buffers are layered above it.

◆ FindMemoryType()

uint32_t chrono::sensor::ChVulkanRTDevice::FindMemoryType ( uint32_t  type_bits,
VkMemoryPropertyFlags  required_flags,
VkMemoryPropertyFlags  preferred_flags = 0 
) const

Choose a memory type carrying all required flags, preferring extra flags when available.

If no supported type also carries preferred_flags, retry with required_flags only.
