Java OpenGL（LWJGL）VBO四元图形崩溃

我目前一直在学习顶点数组和VBO的b/c，我现在知道它比“立即”渲染（如使用glBegin）更好/更快，尽管这要容易得多。我制作了一个小程序（实际上只是一个测试），创建了一个按钮，当您将鼠标悬停在按钮上时，它会改变颜色，但每当我启动它时，程序就会崩溃，并显示以下错误消息：

我的代码

}

这是因为您告诉OpenGL您想要使用颜色数组，所以当OpenGL尝试使用顶点和颜色缓冲区进行渲染时，它失败了，因为您没有绑定颜色缓冲区

这就是你所缺少的

glBindBuffer(GL_ARRAY_BUFFER, vbo_color_handle);
glColorPointer(vertexSize, GL_FLOAT, 0, 0l);

您需要用自己的颜色句柄id替换

vbo\u颜色\u句柄

更好的例子 另外，仅通过查看您的代码，我可以看出您并不完全了解VBO的工作原理，因此这里有一个VBO存储三角形的顶点和颜色并进行渲染的小示例

创建VBO。 这是创建实际顶点和颜色缓冲区并将它们绑定到VBO的代码

int vertices = 3;

int vertex_size = 3; // X, Y, Z
int color_size = 3; // R, G, B

FloatBuffer vertex_data = BufferTools.createFloatBuffer(vertices * vertex_size);
vertex_data.put(new float[] { -1f, -1f, 0f, });
vertex_data.put(new float[] { 1f, -1f, 0f, });
vertex_data.put(new float[] { 1f, 1f, 0f, });
vertex_data.flip();

FloatBuffer color_data = BufferTools.createFloatBuffer(vertices * color_size);
color_data.put(new float[] { 1f, 0f, 0f, });
color_data.put(new float[] { 0f, 1f, 0f, });
color_data.put(new float[] { 0f, 0f, 1f, });
color_data.flip();

vbo_vertex_handle = glGenBuffers();
glBindBuffer(GL_ARRAY_BUFFER, vbo_vertex_handle);
glBufferData(GL_ARRAY_BUFFER, vertex_data, GL_STATIC_DRAW);
glBindBuffer(GL_ARRAY_BUFFER, 0);

vbo_color_handle = glGenBuffers();
glBindBuffer(GL_ARRAY_BUFFER, vbo_color_handle);
glBufferData(GL_ARRAY_BUFFER, color_data, GL_STATIC_DRAW);
glBindBuffer(GL_ARRAY_BUFFER, 0);

渲染VBO。 这是渲染VBO时需要调用的代码

glBindBuffer(GL_ARRAY_BUFFER, vbo_vertex_handle);
glVertexPointer(vertex_size, GL_FLOAT, 0, 0l);

glBindBuffer(GL_ARRAY_BUFFER, vbo_color_handle);
glColorPointer(color_size, GL_FLOAT, 0, 0l);

glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_COLOR_ARRAY);

glDrawArrays(GL_TRIANGLES, 0, vertices);

glDisableClientState(GL_COLOR_ARRAY);
glDisableClientState(GL_VERTEX_ARRAY);

glBindBuffer(GL_ARRAY_BUFFER, vbo_vertex_handle);
glVertexPointer(vertex_size, GL_FLOAT, 0, 0l);

glBindBuffer(GL_ARRAY_BUFFER, vbo_color_handle);
glColorPointer(color_size, GL_FLOAT, 0, 0l);

glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_COLOR_ARRAY);

glDrawArrays(GL_TRIANGLES, 0, vertices);

glDisableClientState(GL_COLOR_ARRAY);
glDisableClientState(GL_VERTEX_ARRAY);
