and glsl-out
only.Expand description
All information to bind a single uniform value to the shader.
Push constants are emulated using traditional uniforms in OpenGL.
These are composed of a set of primatives (scalar, vector, matrix) that are given names. Because they are not backed by the concept of a buffer, we must do the work of calculating the offset of each primative in the push constant block.
Fields§
§access_path: String
GL uniform name for the item. This name is the same as if you were to access it directly from a GLSL shader.
The with the following example, the following names will be generated, one name per GLSL uniform.
struct InnerStruct {
value: f32,
}
struct PushConstant {
InnerStruct inner;
vec4 array[2];
}
uniform PushConstants _push_constant_binding_cs;
- _push_constant_binding_cs.inner.value
- _push_constant_binding_cs.array[0]
- _push_constant_binding_cs.array[1]
ty: Handle<Type>
Type of the uniform. This will only ever be a scalar, vector, or matrix.
offset: u32
The offset in the push constant memory block this uniform maps to.
The size of the uniform can be derived from the type.
