通过使用gl_PointSize来指定要扩大和缩小 [英] Point to grow and shrink by using gl_PointSize

问题描述

我正在尝试通过使用此功能glPointSize()

I'm Trying to grow and shrink an point by using this function glPointSize()

    float i;
    for (i = 0.0; i < 400.0; i ++) {
        glPointSize(i);
    }
    while (i > 0.0) {
        glPointSize(i);
        i--;
    }

这只是一点，不知道如何使它移动?

it just point, Couldn't know how to make it move?

推荐答案

实施对点数有限制. GL_POINT_SIZE_RANGE可用于获取此限制，但通常会小于400.较大的磅值将被限制在此范围内.

Implementations have a limitation on the size of points. The GL_POINT_SIZE_RANGE can be used to fetch this limit, but it will generally be rather less than 400. A larger point size will be clamped to this range.
