ThreeJS: Get useful shader build log

Question

When my ThreeJS custom shaders contains errors, I get the very cryptic INVALID_OPERATION message in the JS console during the rendering stage:

WebGL: INVALID_OPERATION: useProgram: program not valid

Is there a way to get a more useful log, such as the one returned by getShaderInfoLog()?

(To test this quickly, one can add errors in the shaders of this app.)

Answer 1

出于性能原因，three.js R104在编译着色器程序时不再执行错误检查和报告。但是，多个用户抱怨此更改，因此最近已将其还原。在下一个发行版中R105，一切将与以前一样（请参阅迁移指南）。

但是，您可以R104通过设置renderer.debug.checkShaderErrors为手动打开以前的行为true。
