Uploads one encoded id colour (encodePickId's four floats).
Parameters
- encoded: Float32Array
Returns void
- Defined in packages/render-webgl/dist/gl-picking.d.ts:129

setModel

setModel(matrix: Matrix4): void
Uploads one item's world matrix.
Parameters
- matrix: Matrix4
Returns void
- Defined in packages/render-webgl/dist/gl-picking.d.ts:127

setViewProjection

setViewProjection(matrix: Matrix4): void
Uploads projection * view for the pass. Column-major (§7b).

use

use(): void
Makes this the current program. Once per pass, before any upload.

Returns void
- Defined in packages/render-webgl/dist/gl-picking.d.ts:123

`Static`create

create(gl: WebglContext): IdPassProgram
Compiles and links the id program on gl — UnlitProgram.create's contract: throws SHADER_COMPILATION_FAILED (§89) with the driver's log attached, deletes shader objects on every path.
Parameters
- gl: WebglContext
Returns IdPassProgram
