下面是绘制的函数
void Render()
{
static int rotation=0;
GLshort vertexArray[9]={-25,-25,0, 25,-25,0, 0,25,0 };
GLubyte colorArray[12]={255,0,0,0, 0,255,0,0, 0,0,255,0 };
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glTranslatex(0,0,FixedFromInt(-10));
glRotatex(FixedFromInt(rotation++),0,ONE,0);
glEnableClientState(GL_VERTEX_ARRAY);
glVertexPointer(3,GL_SHORT,0,vertexArray);
glEnableClientState(GL_COLOR_ARRAY);
glColorPointer(4,GL_UNSIGNED_BYTE,0,colorArray);
glDrawArrays(GL_TRIANGLES,0,3);
glDisableClientState(GL_VERTEX_ARRAY);
glDisableClientState(GL_COLOR_ARRAY);
eglSwapBuffers(glesDisplay,glesSurface);
}
其中vertexArray指定3个顶点的坐标值,
glVertexPointer(3,GL_SHORT,0,vertexArray);完成三角形的绘制
