WebGL shader precision format test.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

Tests that WebGLShaderPrecisionFormat class and getShaderPrecisionFormat work.


Test that getShaderPrecisionFormat returns a WebGLShaderPrecisionFormat object.

PASS gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.LOW_FLOAT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.MEDIUM_FLOAT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.HIGH_FLOAT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.LOW_INT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.MEDIUM_INT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.HIGH_INT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.FRAGMENT_SHADER, gl.LOW_FLOAT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.FRAGMENT_SHADER, gl.MEDIUM_FLOAT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.FRAGMENT_SHADER, gl.HIGH_FLOAT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.FRAGMENT_SHADER, gl.LOW_INT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.FRAGMENT_SHADER, gl.MEDIUM_INT) instanceof WebGLShaderPrecisionFormat is true
PASS gl.getShaderPrecisionFormat(gl.FRAGMENT_SHADER, gl.HIGH_INT) instanceof WebGLShaderPrecisionFormat is true

Test that getShaderPrecisionFormat throws an error with invalid parameters.

PASS gl.getShaderPrecisionFormat(gl.HIGH_INT, gl.VERTEX_SHADER) generated expected GL error: INVALID_ENUM.

Test that WebGLShaderPrecisionFormat values are sensible.

PASS shaderPrecisionFormat.rangeMin >= 1 is true
PASS shaderPrecisionFormat.rangeMax >= 1 is true
PASS shaderPrecisionFormat.precision >= 8 is true
PASS shaderPrecisionFormat.rangeMin >= 14 is true
PASS shaderPrecisionFormat.rangeMax >= 14 is true
PASS shaderPrecisionFormat.precision >= 10 is true
PASS shaderPrecisionFormat.rangeMin >= 62 is true
PASS shaderPrecisionFormat.rangeMax >= 62 is true
PASS shaderPrecisionFormat.precision >= 16 is true
PASS shaderPrecisionFormat.rangeMin >= 8 is true
PASS shaderPrecisionFormat.rangeMax >= 8 is true
PASS shaderPrecisionFormat.precision == 0 is true
PASS shaderPrecisionFormat.rangeMin >= 10 is true
PASS shaderPrecisionFormat.rangeMax >= 10 is true
PASS shaderPrecisionFormat.precision == 0 is true
PASS shaderPrecisionFormat.rangeMin >= 16 is true
PASS shaderPrecisionFormat.rangeMax >= 16 is true
PASS shaderPrecisionFormat.precision == 0 is true

Test that getShaderPrecisionFormat returns the same thing every call.

PASS shaderPrecisionFormat.rangeMin == shaderPrecisionFormat2.rangeMin is true
PASS shaderPrecisionFormat.rangeMax == shaderPrecisionFormat2.rangeMax is true
PASS shaderPrecisionFormat.precision == shaderPrecisionFormat2.precision is true
PASS successfullyParsed is true
