===Blending===

To output transparent images, i.e. images with alpha, you'll generally want to blend using [[Premultiplied Alpha]]. Rendering in premultiplied alpha prevents your RGB color values from getting mixed with the background color empty pixels.

===Rendering===

For rasterization, ~~we generally~~ render by:

For rasterization, the render loop typically consists of:

# Render opaque objects front-to-back

# Render the shadow map.

# Render transparent objects back-to-front

# Render all opaque objects front-to-back.

## Opaque objects write to the depth buffer.

# Render all transparent objects back-to-front

## Transparent objects do not write to the depth buffer.

Rendering opaque objects front to back minimizes overdraw, where a pixel gets drawn to multiple times in a single frame.

Rendering transparent objects back to front is needed for proper blending of transparent materials.

==Anti-aliasing==

For a high-quality anti-aliasing, you'll generally want to multiple multi-sampling (MSAA).

This causes the GPU to render the depth buffer at a higher resolution to determine the contribution of your fragment shader's color to the final image.
