WebJan 12, 2013 · a highp int can be represented by a highp float. I would recommend you take float s, and pass float s from your program, since it is very likely that any given GPU uses float s to represent int s. If you pass int s, it is very likely that a … WebApr 17, 2024 · The GL_FRAGMENT_PRECISION_HIGH macro should only be defined when the "highp" precision modifier would be valid to use in the fragment shader (so either GLES or GLSL >= 1.30). However, some drivers (nvidia) define it even when the shader will not accept "highp", leading to shader compilation errors.

It has functions to make a request for render () to be called, either immediately with renderNow () or as soon as the event loop has finished processing the current batch of events with renderLater ().
WebDec 7, 2011 · Highp in fragment shaders is an optional part of the OpenGL ES 2.0 spec, so not all hardware supports it (and even when they do, there may be a performance hit.
