}
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.
