Detailed Description
Abstract base class of factories which make camera projection matrices.
Projection matrices are assumed to be constructed after the fashion described here: http://www.songho.ca/opengl/gl_projectionmatrix.html in which the -Z axis points away from the camera along the view axis, +X points to the right, and +Y points up. This is typical for computer graphics, but is different from the assumptions made by Camera::setOrientation().

| virtual float rve_render_client::ProjectionMatrixFactory::getAspectRatio | ( | ) | [inline, virtual] |
Definition at line 56 of file projection_matrix_factory.h.
| virtual rve_msgs::Matrix4 rve_render_client::ProjectionMatrixFactory::makeMatrix | ( | ) | [protected, pure virtual] |
Subclasses should override this to construct and return your custom projection matrix.
Implemented in rve_render_client::OrthographicProjectionFactory, rve_render_client::PerspectiveProjectionFactory, and rve_render_client::CameraInfoProjectionFactory.
| void rve_render_client::ProjectionMatrixFactory::setAspectRatio | ( | float | width_over_height | ) | [virtual] |
The attached camera calls setAspectRatio() from its setAspectRatio().
Definition at line 58 of file projection_matrix_factory.cpp.
| void rve_render_client::ProjectionMatrixFactory::setCamera | ( | Camera * | camera | ) | [private] |
Connect a camera to this factory. This is called by Camera.
Definition at line 52 of file projection_matrix_factory.cpp.
| void rve_render_client::ProjectionMatrixFactory::updateCamera | ( | ) | [protected] |
Subclasses should call this function after a change is made which would affect the output of makeMatrix().
