示例1: ProjectOnMeshBase
// Project an elevated mesh point to the mesh base
private Point3d ProjectOnMeshBase(Point3d p)
{
p = p + this.localOrigin;
p = p.normalize();
p = p * meshBaseRadius - this.localOrigin;
return p;
}示例2: ComputeViewMatrix
public virtual void ComputeViewMatrix()
{
ComputeAbsoluteMatrices();
if (World.Settings.ElevateCameraLookatPoint) {
targetCameraElevation = TerrainElevation*World.Settings.VerticalExaggeration;
curCameraElevation = curCameraElevation + (0.01f*(targetCameraElevation - curCameraElevation));
}
else {
curCameraElevation = 0;
}
// needs to be double precsion
double radius = WorldRadius + curCameraElevation;
double radCosLat = radius*Math.Cos(_latitude.Radians);
LookFrom = new Point3d(radCosLat*Math.Cos(_longitude.Radians), radCosLat*Math.Sin(_longitude.Radians), radius*Math.Sin(_latitude.Radians));
// this constitutes a local tri-frame hovering above the sphere
Point3d zAxis = LookFrom.normalize(); // on sphere the normal vector and position vector are the same
Point3d xAxis = Point3d.cross(cameraUpVector, zAxis).normalize();
Point3d yAxis = Point3d.cross(zAxis, xAxis);
ReferenceCenter = MathEngine.SphericalToCartesianD(Angle.FromRadians(Convert.ToSingle(_latitude.Radians)), Angle.FromRadians(Convert.ToSingle(_longitude.Radians)), WorldRadius);
// Important step !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
// In order to use single precsion rendering, we need to define a local frame (i.e. center of center tile, etc.)
// Vector3d LocalCenter should be defined & initialized in the CameraBase class
// Each time the camera moves, a new local center could be defined
// The local center also has to be subtracted from all the terrain vertices!!!!
relCameraPos = LookFrom - ReferenceCenter;
// Important step: construct the single precision m_ViewMatrix by hand
// We can build the m_ViewMatrix by hand
