v0.1.0 - First Beta Release!

Released 2021-09-11

Added

• rend3: Materials now have a Transparency field that supports Opaque, Cutout, and Blend transparency modes.
• rend3: AlbedoComponent::TextureVertexValue to represent texture * vertex * constant
• rend3: Mipmaps can be generated automatically on the gpu without the user needing to upload them.
• rend3: Renderer::add_texture_2d_from_texture which allows you to make a new texture from a set another texture's mipmaps.
• rend3 & rend3-pbr: Use wgpu-profiler to generate GPU timings that show up as RendererStatistics.
• rend3 & rend3-pbr: Annotate most code with profiling spans.
• rend3 & rend3-pbr: Add a distance field that signifies how much space shadows should take up.
• rend3-pbr: All major rendering spans are labeled and show up in renderdoc
• rend3-pbr: Multisampling support
• rend3-pbr: Support for transparency as well as stable gpu-culling to preserve transparency sort order.

Changed

• rend3: SUBTLE All handles are now refcounted.
  • Handles are now !Copy. Functions taking handles now accept a reference to a handle.
  • If you want to keep something alive, you need to keep the handle to it alive.
  • Objects will keep Materials/Meshs alive.
  • Materials will keep Textures alive.
  • All resources are removed the render() after they are deleted.
• rend3: Externalize all surfaces, adapters, devices, etc.
  • Instead of using a RendererBuilder, construct an Instance/Adapter/Device with rend::create_iad and pass that to Renderer::new.
  • Surfaces are now controlled by the user. There is a convinence function rend3::configure_surface to make this smoother.
• rend3: Texture::width and Texture::height replaced with Texture::size
• rend3: RendererStatistics is now an alias for Vec<wgpu_profiler::GpuTimerScopeResult>
• rend3: Texture::mip_levels was split into mip_count and mip_source allowing you to easily auto-generate mipmaps.
• rend3: Changed limits such that intel gets CPU mode until wgpu#1111 gets resolved.
• rend3-pbr: creation and resizing's resolution argument replaced with options containing resolution and sample count.

Updated

• Dependencies:
  • glam 0.17 -> 0.18

Fixed

• rend3-pbr: Shadow artifacting due to incorrect face culling when rendering shadow passes
• rend3-pbr: CPU mode drawing failed to account for proper vertex offsets
• rend3-pbr: Non-normalized normal maps now work correctly.
• rend3-pbr: Growing the GPU mode texture descriptor list no longer causes panic
• rend3-gltf: albedo-texture UV transform is now respected
• rend3-gltf: image loading now properly caches images

Removed

• rend3: RendererBuilder replaced with explicit calls to Renderer::new.
• rend3: Renderer::delete_* functions were removed in favor of refcounting.
