hoa_video::private_video::ParticleKeyframe Class Reference

Keyframes, consist of a _time, plus various properties. These are used to specify how the properties of a particle vary over time. For example, in most systems, we'll want particles to fade out over their lifetime, so this could be done by creating 2 keyframes, where the alpha component of the 2nd keyframe's _color is zero.

Detailed Description

Keyframes, consist of a _time, plus various properties. These are used to specify how the properties of a particle vary over time. For example, in most systems, we'll want particles to fade out over their lifetime, so this could be done by creating 2 keyframes, where the alpha component of the 2nd keyframe's _color is zero.
