Opengl ES，在按对象渲染时发出 [英] Opengl ES, issue while rendering close by objects

问题描述

我正在Android上使用opengl es.我有一个3D人形模型，可以在上面放置一个发型，这是另一个3D模型.在进行渲染时，我发现在两个对象非常靠近/重合的区域(头发区域)，渲染是不合适的，实际上，我在不同的移动设备上得到了不同的结果.我怀疑这是Z战.是否存在一些使用opengl正确渲染对象附近的解决方案，该解决方案将在所有移动设备上保持一致.我已附上快照以供参考.

I am working with opengl es on android. I have a 3d humanoid model on which i can put a hairstyle which is another 3d model. While rendering i could find that on the area where the two objects are very close/coincides (the head-hair region) the rendering is not proper, in fact i get different results on different mobile devices. I doubt it is z-fighting. Are there some solution for rendering close by objects properly with opengl es which will be consistent across all mobile devices. I have attached a snapshot for reference.

在这里，我有一个面部模型，上面放置了一个头发模型，但是我没有将头发显示在头顶上，而是得到了这种渲染.

Here i have a face model on which i have placed a hair model but instead of showing the hair on top of the head, i get this kind of rendering.

推荐答案

您是否尝试过更改着色器中的float精度?

Have you tried changing the float precision in the shader?

precision highp float; 

例如.我也注意到在不同的手机上会有不同的结果，如果在某些手机上未启用highp，则结果会很差.

for example. I've noticed different results on different handsets as well, and bad results if highp was not enabled on some.

缩放场景也可以解决问题.

Scaling the scene can also solve the issue.
