瘦脸参数怎么传递 我的是vec2的怎么转你的vec4

[INTKILOW]

uniform vec4 u_preCtrlPoints;//pre控制点
uniform vec4 u_curCtrlPoints;//cur控制点
uniform float u_reshapeRadius;//影响半径
uniform float u_reshapeRatio;//强度

在FaceSlenderSample.cpp里面不是写了吗？

就是把两个点的坐标 变成一个坐标 的 xy 和 zw

GLUtils::setVec4(m_ProgramObj, "u_preCtrlPoints",
             LeftSlenderCtlPoint[0] / (float) m_RenderImage.width,
             LeftSlenderCtlPoint[1] / (float) m_RenderImage.height,
             RightSlenderCtlPoint[0] / (float) m_RenderImage.width,
             RightSlenderCtlPoint[1] / (float) m_RenderImage.height);

//   ... 其他代码

 GLUtils::setVec4(m_ProgramObj, "u_curCtrlPoints",
                     leftCurPoint.x / (float) m_RenderImage.width,
                     leftCurPoint.y / (float) m_RenderImage.height,
                     rightCurPoint.x / (float) m_RenderImage.width,
                     rightCurPoint.y / (float) m_RenderImage.height);
