Member Function Documentation

void SpinningCube::draw ( glm::mat4 &  _projectionMatrix )

virtual

Draw function, called every frame.

Calls its parent's draw function.

Reimplemented from vis2::GeometricObject.

Definition at line 34 of file SpinningCube.cpp.

void SpinningCube::update ( double  _deltaT )

virtual

Update function, called every frame.

Parameters

[in]

_deltaT

is the duration of the last frame in seconds. The cube rotates around its vertical axis.

Implements vis2::GeometricObject.

void SpinningCube::updateMm ( glm::mat4 &  _newModelMatrix )

virtual

Function for moving the cube in world space.

Parameters

[in]

_newModelMatrix

is the new model matrix to replace the old one.
