# VkShaderGroupShaderKHR(3) Manual Page

## Name

VkShaderGroupShaderKHR - Shader group shaders

Loading… please wait.

## C Specification

Possible values of `groupShader` in vkGetRayTracingShaderGroupStackSizeKHR are:

    // Provided by VK_KHR_ray_tracing_pipeline
    typedef enum VkShaderGroupShaderKHR {
        VK_SHADER_GROUP_SHADER_GENERAL_KHR = 0,
        VK_SHADER_GROUP_SHADER_CLOSEST_HIT_KHR = 1,
        VK_SHADER_GROUP_SHADER_ANY_HIT_KHR = 2,
        VK_SHADER_GROUP_SHADER_INTERSECTION_KHR = 3,
    } VkShaderGroupShaderKHR;

## Description

- `VK_SHADER_GROUP_SHADER_GENERAL_KHR` uses the shader specified in the group with VkRayTracingShaderGroupCreateInfoKHR::`generalShader`

- `VK_SHADER_GROUP_SHADER_CLOSEST_HIT_KHR` uses the shader specified in the group with VkRayTracingShaderGroupCreateInfoKHR::`closestHitShader`

- `VK_SHADER_GROUP_SHADER_ANY_HIT_KHR` uses the shader specified in the group with VkRayTracingShaderGroupCreateInfoKHR::`anyHitShader`

- `VK_SHADER_GROUP_SHADER_INTERSECTION_KHR` uses the shader specified in the group with VkRayTracingShaderGroupCreateInfoKHR::`intersectionShader`
