Topaz 3.3

• The following shader types have been added:
  • Compute Shader
  • Tessellation Control Shader
  • Tessellation Evaluation Shader
• Wireframe mode is now supported. By default it is disabled, but it can be enabled with a new renderer edit.
• Refactor of TZSLC and various improvements and language features.
  • Namely, TZSL now ships with a standard library!
• TZSLC no longer links against Topaz.
• textc has been removed, and re-added as a separate repository submodule.
• Renderer outputs have now been properly implemented. You can set the renderer output to an image output which can render into an existing image components. This allows a renderer to use the result of another.
• Added following functionality to Renderer edits:
  • Compute Edits, allowing you to set the compute kernel dimensions on-demand
  • Renderer State Edits, allowing you to set some renderer state on-demand.
    • At present, this only includes the ability to toggle wireframe mode rendering.
• Added the following demos:
  • tz_blur_triangle_demo. Draws a single triangle, but blurs it so it looks like two. This is achieved by setting the output of a Renderer to an image component, and then performing post-processing in a second renderer.
  • tz_compute_demo. Contains a buffer resource which a compute shader constantly changes. The buffer data is used to set the colour of each window pixel.
  • tz_terrain_demo. Renders a pretty, low-poly terrain with a single 4-triangle draw-call. This is achieved by using the new tessellation shaders.
