create plane不同的参数渲染不正确 #5

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
SampleWindow底部的plane，把创建参数改成如下，会出现如图的bug
：

        planar_mesh = create_planar(
            hsr.get(), 
            vec3(-3.0f, -1.0f, -3.0f), 
            vec3(6, 0.0f, 0.0f), 
            vec3(0.0f, 0.0f, 6),
            1, 1, true
            );
原来的参数是
        planar_mesh = create_planar(
            hsr.get(), 
            vec3(-3.0f, -1.0f, -3.0f), 
            vec3(0.5f, 0.0f, 0.0f), 
            vec3(0.0f, 0.0f, 0.5f),
            20, 20, true
            );
原来是20*20个矩形共800个三角形组成一个平面。改成2个三角��
�组成一个平面后出现如图的bug

This defect pointed out by anlaysis is caused by titing engine.
Some solutions, taking the clip stage at the front of tiling or changing the 
tiling
algorithm can fix this bug.

Fixed after I modified the tiling algorithm.
