Overview

CC3ScalableMeshParticle is a type of CC3MeshParticle that can be scaled.

This clas is distinct from CC3MeshParticle so that mesh particle that do not require scaling do not have to carry storage for scaling information.

Tasks

Properties

isTransformRigid

Returns whether the current transform applied to this particle is rigid.

@property (nonatomic, readonly) BOOL isTransformRigid

Discussion

A rigid transform contains only rotation and translation transformations and does not include any scaling transformation. For the transform to be rigid, this particle must have unity scaling.

Declared In

CC3MeshParticles.h

isUniformlyScaledLocally

Indicates whether current local scaling (via the scale property) is uniform along all axes.

@property (nonatomic, readonly) BOOL isUniformlyScaledLocally

Declared In

CC3MeshParticles.h

scale

The scale of the particle in each dimension, relative to the emitter.

@property (nonatomic, assign) CC3Vector scale

Discussion

Unless non-uniform scaling is needed, it is recommended that you use the uniformScale property instead.

Declared In

CC3MeshParticles.h

uniformScale

The scale of the particle, uniform in each dimension, relative to the emitter.

@property (nonatomic, assign) GLfloat uniformScale

Discussion

Unless non-uniform scaling is needed, it is recommended that you use this property instead of the scale property.

If non-uniform scaling is applied via the scale property, this uniformScale property will return the length of the scale property vector divided by the length of a unit cube (sqrt(3.0)), as an approximation of the overall scaling condensed to a single scalar value.
