在OpenGL中渲染透明对象 [英] Rendering transparent objects in OpenGL

问题描述

我正在尝试使用opengl渲染某些3d对象.要求是我需要隐藏在另一个透明对象之后的所有透明对象.所有三角形都在单个三角形缓冲区中，并且将立即绘制.请给点灯.

Iam trying to render some 3d objects using opengl. Requirement is that i need to hide all the transparent objects which are z-behind another transparent object. All the triangles are in single triangle buffer and will be drawn at once. Please throw some light.

推荐答案

尝试使用glDepthMask():

Try using glDepthMask():

    //Render all opaque objects
    glDepthMask(false); //disable z-testing
    //Render all transparent objects*
    glDepthMask(true); //enable z-testing (for the next frame)

*从技术上讲，您应该从后到前渲染透明对象，但如果不这样做，则很少引起注意.

*Technically, you should render the transparent objects from back to front, but it is rarely noticeable if you don't.
