WebOur shaders are going to assume that there is only 1 active non-global ambient light. Legacy OpenGL allows at least 8 active lights, all of which would be involved in the ambient light calculations (when enabled). The material's ambient value can be thought of as "how much of the ambient light does the material re-emit" (as opposed to absorbing). WebThe vertex shader now receives a light position instead of a light direction, and it must compute the light’s direction for each vertex. It is assumed that the light’s position is in camera space. Once we move the vertex position to the same space, the direction computation is straightforward: light direction = light position – vertex position.

WebThe vertex shader to implement this formula will use the lights properties, namely its position, and diffuse intensity. It will also use the materials diffuse setting. Hence to use this shader just set the light as usual in OpenGL. Note however that since we’re not using the fixed functionality, there is no need to enable the lights.

WebThis is called per-fragment lighting or just fragment lighting. This is pretty simple, conceptually. We simply need to do the lighting computations in the fragment shader.

SPIR-V is intended to provide developers with the freedom to develop their shaders in any language they want (as long as it can be compiled to SPIR-V), and avoid the need for an OpenGL (or Vulkan) implementation to provide compilers for multiple languages.
