尝试进行深度附加时，帧缓冲状态错误（返回36054）

Question

以下是为阴影贴图设置帧缓冲的代码，但在检查帧缓冲状态时它返回36054。有什么想法吗？

//bind framebuffer for shadow mapping
gl.glGenFramebuffers(1, framebuff);
gl.glBindFramebuffer(GL4.GL_FRAMEBUFFER, framebuff.get(0));

gl.glGenTextures(1, textureBuff);

gl.glBindTexture(GL4.GL_TEXTURE_2D, textureBuff.get(0));
gl.glTexStorage2D(GL4.GL_TEXTURE_2D, 1, GL4.GL_DEPTH_COMPONENT32F, displayWidth, displayHeight);
gl.glTexParameteri(GL4.GL_TEXTURE_2D, GL4.GL_TEXTURE_MAG_FILTER, GL4.GL_LINEAR);
gl.glTexParameteri(GL4.GL_TEXTURE_2D, GL4.GL_TEXTURE_MIN_FILTER, GL4.GL_LINEAR);//GL_LINEAR_MIPMAP_LINEAR
gl.glTexParameteri(GL4.GL_TEXTURE_2D, GL4.GL_TEXTURE_WRAP_S, GL4.GL_CLAMP_TO_EDGE);
gl.glTexParameteri(GL4.GL_TEXTURE_2D, GL4.GL_TEXTURE_WRAP_T, GL4.GL_CLAMP_TO_EDGE);

gl.glTexParameteri(GL4.GL_TEXTURE_2D, GL4.GL_TEXTURE_COMPARE_MODE, GL4.GL_COMPARE_REF_TO_TEXTURE);
gl.glTexParameteri(GL4.GL_TEXTURE_2D, GL4.GL_TEXTURE_COMPARE_FUNC, GL4.GL_LEQUAL);
gl.glFramebufferTexture(GL4.GL_FRAMEBUFFER, GL4.GL_DEPTH_ATTACHMENT, textureBuff.get(0), 0);
gl.glDrawBuffer(GL4.GL_NONE);

if(gl.glCheckFramebufferStatus(GL4.GL_FRAMEBUFFER) != GL4.GL_FRAMEBUFFER_COMPLETE)
    return gl.glCheckFramebufferStatus(GL4.GL_FRAMEBUFFER);

固定。在重塑函数期间设置了displayWidth和displayHeight，并且在重塑函数中分配之前默认为0，因此在设置缓冲区时它为0，这违反了规则。
