示例1: computeAttractorPosition
void gpuPSApp::computeAttractorPosition()
{
// The attractor is positioned at the intersection of a ray
// from the mouse to a plane perpendicular to the camera.
float t = 0;
Vec3f right, up;
mMayaCam.getCamera().getBillboardVectors(&right, &up);
CameraPersp cam = mMayaCam.getCamera();
float u = mMousePos.x / (float) getWindowWidth();
float v = mMousePos.y / (float) getWindowHeight();
Ray ray = cam.generateRay(u , 1.0f - v, cam.getAspectRatio() );
if (ray.calcPlaneIntersection(Vec3f(0.0f,0.0f,0.0f), right.cross(up), &t)) {
mAttractor.set(ray.calcPosition(t));
}
}
示例2: mouseDrag
void RodSoundApp::mouseDrag(MouseEvent event)
{
if (!running) return;
Vec2i mouse = event.getPos();
Vec2i windowSize = getWindowSize();
Ray r = cam.generateRay((real)mouse.x/windowSize.x,
1.0 - (real)mouse.y/windowSize.y,
getWindowAspectRatio());
float t;
if(!r.calcPlaneIntersection(targetPos, targetPos-eyePos, &t)) {
std::cerr << "Mouse ray did not intersect plane!\n";
}
mousePosition = r.calcPosition(t);
}
