C++ (Cpp) createFrameBuffers示例

示例#1

文件： GLRenderer.cpp 项目： JSMilton/PerlinFire

void GLRenderer::reshape(int width, int height) {
    glViewport(0, 0, width, height);
    mViewWidth = width;
    mViewHeight = height;
    mProjectionMatrix = glm::perspective(45.0f, (float)width/(float)height, 0.1f, 100.0f);
    mViewMatrix = glm::lookAt(glm::vec3(0,0,3), glm::vec3(0,0,0), glm::vec3(0,1,0));
    
    glm::vec4 fwidth;
    fwidth = mProjectionMatrix * mViewMatrix * glm::vec4(mViewWidth, mViewHeight, 0, 1);
    mMouseWidth = fwidth.x /= fwidth.w;
    mMouseHeight = fwidth.y /= fwidth.w;
    createFrameBuffers();
}

示例#2

    mViewWidth = width;
    mViewHeight = height;
    mHeightDividedByK = height / mK;
    mWidthDividedByK = width / mK;
    mProjectionMatrix = glm::perspective(45.0f, (float)width/(float)height, 0.1f, 100.0f);
    mViewMatrix = glm::lookAt(glm::vec3(0,0,20), glm::vec3(0,0,0), glm::vec3(0,1,0));
    computeMaxSampleTapDistance();
    
    if (!isLive){
        createFrameBuffers();
    }
