| G3DReal | focalDistance () |
| |
| G3DReal | lensDiameter () |
| |
| int | maxDepth () |
| |
| virtual GDomNode * | serialize (GDom *pDoc) const |
| | serializes this object More...

| |
| void | setLensDiameter (G3DReal val) |
| |
| void | setMaxDepth (int val) |
| |
| | GCamera (int width, int height) |
| | width and height specify the size of the image that this camera will produce More...
|
| |
| | GCamera (GDomNode *pNode) |
| | deserializing constructor More...
|
| |
| virtual | ~GCamera () |
| |
| void | computeRayDirection (int x, int y, G3DVector *pOutRay) |
| | Computes the direction that a ray must travel from lookFromPoint() for the specified pixel coordinates (relative to the bottom-left corner of the view image). Note that the ray is not normalized. More...
|
| |
| G3DReal | halfViewHeight () |
| | Returns tan(viewAngle / 2) More...
|
| |
| int | imageHeight () |
| | Returns the height of the 2-D image this camera will produce. More...
|
| |
| int | imageWidth () |
| | Returns the width of the 2-D image this camera will produce. More...
|
| |
| const G3DVector * | lookDirection () |
| | Returns the direction in which this camera is facing. More...
|
| |
| G3DVector * | lookFromPoint () |
| | Returns a reference to the location of this camera. (You can set the values in the vector this returns to move the camera.) More...
|
| |
| void | project (const G3DVector *pPoint, G3DVector *pOut) |
| | Projects the 3D point onto the canvas. The x and y position in the output vector specify the location where the point projects onto the camera's canvas (positive x goes to the right with 0 at the left side, positive y goes up with 0 at the bottom). The z position specifies the distance from the camera. If the z position is <= 0, then x and y are set to 0. More...
|
| |
| void | setDirection (G3DVector *pDirection, G3DReal rollRads) |
| | Specifies the direction that the camera faces, and the roll in radians. (If rollRads is zero, then the horizon of the XZ-plane would appear as a horizontal line with positive Y above and negative Y below.) More...
|
| |
| void | setDirection (G3DVector *pDirection, G3DVector *pUpVector) |
| | If pUpVector is not orthogonal to pDirection, it will be changed to the nearest vector that is orthogonal to pDirection. More...
|
| |
| void | setImageSize (int width, int height) |
| | Specifies the size of the 2-D image this camera will produce. More...
|
| |
| void | setViewAngle (G3DReal val) |
| | This is the vertical view angle in radians. More...
|
| |
| const G3DVector * | viewSideVector () |
| | Returns the right side vector with respect to this camera. More...
|
| |
| const G3DVector * | viewUpVector () |
| | Returns the up vector with respect to this camera. More...
