Alternative stencil behavior to allow logical `AND`

3

The planned simplied draw state in https://github.com/PistonDevelopers/graphics/issues/996 suggests using: - replace operator for `Stencil::Clip` - equality comparison for `Stencil::Inside` - non-equality comparison for `Stencil::Outside` This design allows up to 255...

Because of the [design constraints in APIs with PSOs](https://github.com/PistonDevelopers/graphics/issues/1030), the behavior of `Stencil` in the [simplified draw state](https://github.com/PistonDevelopers/graphics/issues/996) is limited to the set of PSOs in the backend. Supporting all...

This issue is describing the inherent constraints of immediate design for blending, using next-gen graphics APIs backends. ### Next-gen APIs are designed for knowing the blending equation upfront 1. Next-gen...

Add Ability to Draw Dots

I am making a "game" that is like the game of life. I don't have a fast enough GPU to render a full screen of one pixel rectangles quickly. If...

Add a `Plot` type for plotting 2D functions?

4

I've come across a few cases where it'd be nice to be able to draw straight from some generic `FnMut`, i.e. ``` rust let f = |x: f64| x.sin() *...

Use associated type for draw state

1

Blending is not usually required for widgets, and using a custom draw state means overhead. Perhaps we could use the native draw state? - A software rasterizer might want full...

The clip draw states are static, which means if you pre-multiply alpha you get wrong blending equations. Perhaps we should change the design such that clipping modified the draw state...

Use default generic float set to `Scalar`

1

Instead of setting the float type to `Scalar` explicitly, we might be able to use a default generic and lets you use the library with `f32`. - [x] `math::Matrix2d` =>...

The idea is to allow greater customization of graphics back-ends. This can be: - Custom shaders - Custom draw parameters such as uniforms By using `Any`, you can use it...

Pre-multiplied alpha is a technique that allows correct alpha blending when rendering on top of transparent surfaces. It pre-multplies the RGB colors in the fragment shader with the alpha channel,...
