Detailed Description

Resource containing instances information for rendering.

Texture indices are used to select the texture to use for each instance, the index refers to a texture in RenderResourceTextures. If the index is out of range, the texture will be replaced by a bad texture. This parameter is optional, if set to nullptr, all textures in RenderResourceTextures will be bound to each instance.

Vertex count is used to select the number of vertices to use for each instance. If the vertex count is 0, the vertex count will be set to the vertex count of the vertex buffer.

Dynamic descriptors are used to set dynamic descriptors for each instance. Dynamic descriptors are used to set dynamic uniform buffers. This parameter is optional, if set to nullptr, no dynamic descriptors will be set.

◆ setFirstInstance()

void fge::RenderResourceInstances::setFirstInstance ( uint32_t firstInstance )

inlineconstexpr

Set the first instance value for the draw call.

Appliqued if hasUniqueDrawCall() is true without indirect buffer. Appliqued has an offset if hasUniqueDrawCall() is false.

Parameters

firstInstance The first instance value
