MVP Tracking issue

[druskus20]

MVP

• Sync redraws to monitor refresh rate #2
• Add an option to flip the volume
• Implement a simple volume renderer
• Make a module for the shader + pipeline + volume(?) #5
• Support multiple rendering algorithms
• Camera movement #6
• Better transfer function #16
• Phong shading and color mixing properly
• Refactor code to make "GPU" variants of resources, and a trait ToGPU #22
• Add parameters to the compute shader #4
• Support segmented volumes #25
• Implement importance driven volume rendering #15
• Add benchmarking capabilities #3
• Use egui to display UI #13
• Benchmark the project and generate graphs

Problems

• Importance driven with cone is slow #32
• Currently not using zfar / znear at least in some shaders #33
• Antialias / better sampling #29

Refactors

• Refactor texture creation outside of render pipeline
• TF with TransferFunctionBuilder #19
• Make each gpu_object care about it's rendering stuff - effectively move everything out of compute_base #20
• Make volume and transfer function a compute_base thing #21
• ToGpu trait? #31
• Switch to a better error library #30
• Go back to the default limit for bindgroups (6->4)

Extras:

• Multi pass? #14
• Hot reload shaders #26
• Hot reload volumes #27
• Add a way to toggle some coloring for the importance pass? #28
