Release Notes v0.2.2 (1/19/23)

• Additions and Changes:
  • Scene files can now be saved to any directory inside of your project instead of the default LOVR save directory.
  • Every Object in a scene now has a selectionCollider applied to it. This is a lovr box collider that is always locked to the pose of the parent node. This change doesn’t have much of a use yet but will come in handy when I begin working on the level editor, allowing users to highlight their mouse over objects to click and select them.
  • PCF filtering for shadowmaps has been smoothed even further using this method by Nvidia. Here’s a comparison of the old and new method:
  • 
  • There are some drawbacks with this method though, such as slight shadow grain, but this can be iterated on in future versions.
• Bug Fixes:
  • Bodies had their global and local transform calculations set incorrectly in previous versions. This has been fully fixed to my knowledge, but may require further testing.
  • When a parent Node has it’s transform updated, all child Nodes now also have their transforms updated. Though this is also done in the Scene:update() method, this new change ended up being necessary for dynamically transforming Objects.
    

    Release Notes v0.2.1 (1/17/23)

• Particle objects have been added!
  • Particle objects are rendered using a soft particle system by comparing depth buffers.
  • Particle objects have a multitude of options, meaning their appearance can be highly customized.
• Changes to the Node Class:
  • visible has been added as a property to all nodes, meaning they can be toggled on and off during rendering.
  • Model objects now have canCastShadows as a property.
    

    Release Notes v0.2.0 (1/12/23):

• Scene Graph system has been completely rewritten!
  • Objects now have child and parent relationships.
  • Models now include texturing modes for either tiling textures along the surface of a model or simply applying a UV map.
• Transform Class and system has been massively improved:
  • Objects include a globalTransform and localTransform. localTransform is offset from the parent globalTransform.
  • Objects now have methods for easily setting their Global and Local transform matrix, position, rotation (including looking at a target or toward a direction), or scale.
• Scene saving and loading is implemented!
  • Scene Objects can now be saved to lua files with the aid of the serpent library.
  • These scenes can be easily loaded from any filepath as well.
