Detailed Description

Set of shaders used for interface drawing.

2D shaders are not expected to work in 3D. 3D shaders can work with 2D geometry and matrices.

INST suffix means instance, which means the shader is build to leverage instancing capabilities to reduce the number of draw-calls.

For full list of parameters, search for the associated #ShaderCreateInfo. Example: GPU_SHADER_ICON is defined by GPU_SHADER_CREATE_INFO(gpu_shader_icon) Some parameters are builtins and are set automatically (ex: ModelViewProjectionMatrix).

Enumeration Type Documentation

eGPUBuiltinShader

enum eGPUBuiltinShader

Enumerator
GPU_SHADER_TEXT	Glyph drawing shader used by the BLF module.
GPU_SHADER_KEYFRAME_SHAPE	Draws keyframe markers. All markers shapes are supported through a single shader.
GPU_SHADER_SIMPLE_LIGHTING	Draw solid mesh with a single distant light using a clamped simple dot product.
GPU_SHADER_ICON	Draw an icon, leaving a semi-transparent rectangle on top of the icon.
GPU_SHADER_2D_IMAGE_RECT_COLOR	Draw a texture with a uniform color multiplied.
GPU_SHADER_2D_IMAGE_DESATURATE_COLOR	Draw a texture with a desaturation factor.
GPU_SHADER_ICON_MULTI	Draw a group of texture rectangle with an associated color multiplied.
GPU_SHADER_2D_CHECKER	Draw a two color checker based on screen position (not UV coordinates).
GPU_SHADER_2D_DIAG_STRIPES	Draw diagonal stripes with two alternating colors.
GPU_SHADER_3D_LINE_DASHED_UNIFORM_COLOR	Draw dashed lines with custom dash length and uniform color.
GPU_SHADER_3D_DEPTH_ONLY	Draw triangles / lines / points with only depth output.
