异常访问冲突？

Question

我不明白，我正在学习 LWJGL，但是当我输入该代码时：

public void render()
    {
        glBindBuffer(GL_ARRAY_BUFFER, vID);
        glVertexPointer(3, GL_FLOAT, 0, 0L);

        glEnableClientState(GL_VERTEX_ARRAY);

        glDrawArrays(GL_QUADS, 0, CHUNK_SIZE * CHUNK_SIZE * CHUNK_SIZE * (3 * 4 * 6));

        glDisableClientState(GL_VERTEX_ARRAY);

    }

java 投掷：

我该如何解决类似的问题？我启用客户端状态并且 vertexPointer 浮点数为“3”。我真的需要一些帮助 x.x 非常感谢

LWJGL 中的访问冲突主要是由缓冲区大小和渲染调用计数不合适引起的。

您应该检查您的 vID 是否真的包含要绘制的 CHUNK_SIZE * CHUNK_SIZE * CHUNK_SIZE * (3 * 4 * 6) 个元素。参见 here。

我猜它应该是 CHUNK_SIZE * CHUNK_SIZE * CHUNK_SIZE * (4 * 6) : CHUNK_SIZE^3 个元素，有 6 个边，每个边由 4 个顶点组成。
