Member Function Documentation

bool chrono::opengl::ChOpenGLWindow::DoStepDynamics ( double time_step )

Perform a dynamics step, the user needs to use this so that pausing the simulation works correctly.

Parameters

time_step integration step size

void chrono::opengl::ChOpenGLWindow::Initialize	(	int	size_x,
		int	size_y,
		const char *	title
	)

Initialize the window and set up the OpenGL viewer class.

Parameters

void chrono::opengl::ChOpenGLWindow::SetCamera	(	ChVector<>	pos,
		ChVector<>	look,
		ChVector<>	up,
		float	scale = `0.5f`,
		float	near_clip_dist = `0.1f`,
		float	far_clip_dist = `1000.0f`
	)

Set the camera position, look at and up vectors.

Parameters

pos	The position of the camera
look	The point that the camera is looking at
up	The up vector associated with the camera
scale	zoom level
near_clip_dist	near clipping distance
far_clip_dist	far clipping distance

void chrono::opengl::ChOpenGLWindow::StartDrawLoop ( double time_step )

This starts the drawing loop and takes control away from the main program.

This function is the easiest way to start rendering.

Parameters

time_step integration step size
