let result = (a + b) >>> 0;
gl.uniform4fv(shader.uniform('uValue1'), setVec4FromUint32(vec4.create(), a));
gl.uniform4fv(shader.uniform('uValue2'), setVec4FromUint32(vec4.create(), b));
tester.execute();
let value = tester.readUint32();
expect(value).toEqual(result, `${a} + ${b}`);
}示例2: testOffset
function testOffset(x: number) {
let value = data[x];
gl.uniform1f(shader.uniform('uOffset'), x);
gl.uniform4fv(shader.uniform('uExpected'), setVec4FromUint32(new Float32Array(4), value));
