OpenGL ES代码修改
我正在创建一个 opengl ES 项目，我正在尝试显示一些纹理，一切都很好，但问题是内存的使用，每 5 秒增量几乎 1 Mb，我认为我做错了什么，我我没有使用任何这个
// Generate the vertex buffer object (VBO)
glGenBuffers(1, &ui32Vbo);
// Bind the VBO so we can fill it with data
glBindBuffer(GL_ARRAY_BUFFER, ui32Vbo);
// Set the buffer's data
// Calculate verts size: (3 vertices * stride (3 GLfloats per each vertex))
glBufferData(GL_ARRAY_BUFFER, uiSize, verts, GL_STATIC_DRAW);
// Bind the VBO so we can fill it with data
glBindBuffer(GL_ARRAY_BUFFER, ui32Vbo);
glEnableClientState(GL_VERTEX_ARRAY);
glVertexPointer(3, GL_FLOAT, 20, 0); // Stride = 20 bytes
glBindTexture(GL_TEXTURE_2D, textID);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glTexCoordPointer(2, GL_FLOAT, 20, (void *)12);
glDrawArrays(GL_TRIANGLE_FAN, 4, 4);
// Bind the VBO so we can fill it with data
glBindBuffer(GL_ARRAY_BUFFER, 0);
非常感谢！！！
I´m creating an opengl ES project and I´m trying to show some textures, all works good but the problem is the use of the memory, every 5 seconds increments almost 1 Mb, I think I´m doing something wrong, I´m not using any of this apple recommendations I will tray for sure, but I want to know if my code have some bug, there is how I´m paiting:
// Generate the vertex buffer object (VBO)
glGenBuffers(1, &ui32Vbo);
// Bind the VBO so we can fill it with data
glBindBuffer(GL_ARRAY_BUFFER, ui32Vbo);
// Set the buffer's data
// Calculate verts size: (3 vertices * stride (3 GLfloats per each vertex))
glBufferData(GL_ARRAY_BUFFER, uiSize, verts, GL_STATIC_DRAW);
// Bind the VBO so we can fill it with data
glBindBuffer(GL_ARRAY_BUFFER, ui32Vbo);
glEnableClientState(GL_VERTEX_ARRAY);
glVertexPointer(3, GL_FLOAT, 20, 0); // Stride = 20 bytes
glBindTexture(GL_TEXTURE_2D, textID);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glTexCoordPointer(2, GL_FLOAT, 20, (void *)12);
glDrawArrays(GL_TRIANGLE_FAN, 4, 4);
// Bind the VBO so we can fill it with data
glBindBuffer(GL_ARRAY_BUFFER, 0);
Thank you very much!!!

您应该只生成一次顶点缓冲区对象，然后使用它进行绘制。
看来你每一帧都创建一个新的。
You should generate the vertex buffer object only once, the use it draw.
It seems you create a new one each frame.
