geo-particle

Description

geo-particle tests point size and line width using a simple particle system. Each particle can be a line or a point of various widths. This demo also tests texture points using GX_TO_ZERO. The color of each particle is point-sampled from a texture.

Coverage

Functions	Parameters	Description
`GXSetPointSize`	`width`	Specifies the width using a `u8`-type value. Specify a width value in 1/6 steps from 0 through 42.5.
`GXSetPointSize`	tex_offsets	Ignored (`GX_TO_ZERO` if texture is used).
`GXSetLineWidth`	size	Specifies the width using a `u8`-type value. Specify a width value in 1/6 steps from 0 through 42.5.
`GXSetLineWidth`	tex_offsets	Ignored.

Using the Demo

PAUSE exits the test.

The main stick changes the orientation of the particle emitter.

The X button toggles the control mode.

Particle Type Control

The B button selects particle type (points, lines, texture points).

Point Size Animation Control

The B button selects size animation type (constant size per particle, animated-growing smaller, animated-growing larger).

The A button pauses the animation while pressed down.

The L/R button changes the point size.
