Methods

addTexture

addTexture(
    location: string,
    mapFrom?: Rect,
    mapTo?: Rect,
    mapToBuffer?: string,
    points?: number[],
    repeat?: boolean,
    onLoad?: (() => void) | null,
    loadColor?: TypeColor,
): void
Buffer a texture for the shape to be painted with.
Parameters
- location: string
- mapFrom: Rect = ...
- mapTo: Rect = ...
- mapToBuffer: string = 'a_vertex'
- points: number[] = []
- repeat: boolean = false
- onLoad: (() => void) | null = null
- loadColor: TypeColor = ...
Returns void
- Defined in src/js/figure/DrawingObjects/GLObject/GLObject.ts:291

getUniform

getUniform(uniformName: string): number[]
Get the current value of a uniform
Parameters
- uniformName: string
Returns number[]
Overrides DrawingObject.getUniform
- Defined in src/js/figure/DrawingObjects/GLObject/GLObject.ts:632

addUniform

addUniform(
    uniformName: string,
    length?: 1 | 2 | 3 | 4 | 16,
    type?: TypeGLUniform,
    initialValue?: number | number[] | null,
): void
Add a uniform.

Length 16 corresponds to a 4x4 matrix and can only be 'FLOAT_VECTOR' type.
Parameters
- uniformName: string
  The variable name used in the shader
- length: 1 | 2 | 3 | 4 | 16 = 1
  (1) number of values in uniform
- type: TypeGLUniform = 'FLOAT'
  type of value. Use '_VECTOR' suffix if using vector methods on the uniform in the shader ('FLOAT').
- initialValue: number | number[] | null = null
  initial value to use for uniform - if null then uniform will be all 0 (null)
Returns void
- Defined in src/js/figure/DrawingObjects/GLObject/GLObject.ts:651
