Public Methods | |
| Viewpoint () | |
| Constructor. | |
| void | setExtrinsics (const ColVector3 up_vector, const Vertex center_of_projection, const Vertex lookat_point) |
| Sets the extrinsic camera parameters, which are those specified by gluLookAt. | |
| void | setIntrinsics (double vert_fov, double width_over_height, double near_plane, double far_plane) |
| Sets the intrinsic camera parameters, which are those specified by gluPerspective. | |
| void | loadFromFiles (const char *photo_filename, const char *silhouette_filename) |
| Loads a color image, and optionally a silhouette image. | |
| unsigned int | getWidth () const |
| Gets the width of the picture, in pixels. | |
| unsigned int | getHeight () const |
| Gets the height of the picture, in pixels. | |
| Vertex | getLookatPoint () const |
| Gets the point that is being looked at in this image. This is usually an approximation, and indicates direction more than anything else. | |
| Vertex | getCenterOfProjection () const |
| Gets the center of projection, which is where the camera would be if it were a pinhole camera. | |
| ColVector3 | getUpVector () const |
| Gets a normalized vector that points up relative to the camera. | |
| double | getDistanceToObject () const |
| Returns the distance between the center of projection and the lookat point. | |
| RgbByte | colorAt (unsigned int u, unsigned int v) const |
| Gets the color at a given position in the image. | |
| bool | pixelIsTransparent (unsigned int u, unsigned int v) const |
| Gets whether the pixel at a given position is transparent. | |
| bool | hasSilhouette () const |
| Returns whether this viewpoint was loaded with an associated silhouette. | |
| double * | getModelviewMatrix () const |
| Get the modelview matrix that corresponds to this view, in OpenGL (column-major) format. | |
| double * | getProjectionMatrix () const |
| Get the projection matrix that corresponds to this view, in OpenGL (column-major) format. | |
Public Attributes | |
| std::vector< unsigned int > | imageBuffer |
| This array of integers serves as an item buffer. It is actually a flattened 2d array of per-pixel identifiers. | |
| PortablePixMap | photo |
| The color image that corresponds to this view. | |
