Second additional release for 2021 HT1

New features

• Add content to the default landing page of the documentation;
• Parse common material constants when loading custom objects via loadObjects();
• Allow per-axis movement and rotation speed for the camera;
• Allow orbiting cameras for Lab 3 and 4 of EDAF80;
• Use Uniform Buffer Objects in EDAN35/Lab2 for transforms and light attributes.

Improvements

• Several debug improvements:
  • Error out if a node is lacking a VAO or program rather than silently not rendering it;
  • Un-ignore certain warning messages.
• Swap “sprint” and “walk” modifiers, so they match the behaviour found in most games;
• Improve the documentation of TRSTransform;
• Several improvements to EDAN35/Lab2, especially on the performance side.

Changes

• Use a regular sampler2D for the shadow map during light accumulation;
• Automatically build the documentation using GitHub Actions and host it using GitHub Pages.

Fixes

• Increase the camera far plane in EDAN35/Lab2 to avoid artefacts during lighting;
• Use a single rotation tracking system for the camera, allowing Look*() methods to be used and not instantly overwritten by other rotations;
• Set shadowmap_texel_size;
• Make the angular spacing between light sources in EDAN35/Lab2 dependent on the maximum amount of light sources.

Dependencies updates

• Update assimp to 5.1.2, and increase the requirement to 5.1.
