This example isn’t the most efficient way to draw a circle, especially if you intend to do it repeatedly. The graphics commands used are typically very fast, but this code calculates an angle and calls the sin() and cos() routines for each vertex; in addition, there’s the loop over...

该程序使用了GLFW的函数来创建一个800x600的窗口,并设置了标题为"OpenGL Half Circle"。然后,我们使用glfwMakeContextCurrent函数将该窗口设置为当前上下文。 绘制半圆 接下来,我们将在渲染循环中使用OpenGL的函数来绘制半圆。我们将使用glBegin和glEnd来定义一个绘制区域,并使用glVertex2f来绘制半圆的顶点。
/* Reset after we have completed a circle */ if (angle >= 360.0f) { angle = 0.0f; } glPushMatrix(); glLoadIdentity(); /* Move to 0,0,-30 , rotate the robot on its y axis, draw the robot, and dispose of the current matrix. */ glTranslatef(0.0f, 0.0f, -30.0f); glRotate...
在OpenGL ES中绘制纹理圆可以通过以下步骤实现: 1. 创建一个圆的顶点数组:通过计算圆上的点的坐标,可以得到一个圆的顶点数组。可以使用三角形扇形来绘制圆,其中圆心作为扇形的中心点,每个顶点的...
