Member Function Documentation

ChVector chrono::ChCamera::GetAimPoint ( )

Gets the position of the target point (aim point).

Expressed in the local coordinate system (ex. of the owner ChBody, of ChAssetLevel,..)

double chrono::ChCamera::GetHVratio ( )

Gets the Horizontal/Vertical size ratio.

Default = 4/3. For instance, 4/3 can be used if rendering to 800x600 images with square pixels.

bool chrono::ChCamera::GetOrthographic ( )

If 'true' it means that perspective projection is disabled and you get a 'flat' view.

This must be supported by the visualization system. By default is 'false'.

ChVector chrono::ChCamera::GetPosition ( )

Gets the position of the observer (eye point).

Expressed in the local coordinate system (ex. of the owner ChBody, of ChAssetLevel,..)

ChVector chrono::ChCamera::GetUpVector ( )

Gets the position of the 'up' direction of the camera (default is vertical, VECT_Y) Expressed in the local coordinate system (ex.

of the owner ChBody, of ChAssetLevel,..)

void chrono::ChCamera::SetAimPoint ( ChVector<>  mv)

Sets the position of the target point (aim point).

Expressed in the local coordinate system (ex. of the owner ChBody, of ChAssetLevel,..)

void chrono::ChCamera::SetAngle ( double  mdeg)

Sets the opening angle of the lenses, in degrees, on horizontal direction.

Ex. 60=wide angle, 30=tele, etc.

void chrono::ChCamera::SetHVratio ( double  mf)

Sets the Horizontal/Vertical size ratio.

Default = 4/3. For instance, 4/3 can be used if rendering to 800x600 images with square pixels.

void chrono::ChCamera::SetOrthographic ( bool  mb)

Set to 'true' if you want to disable perspective and get a 'flat' view.

This must be supported by the visualization system. By default is 'false'.

void chrono::ChCamera::SetPosition ( ChVector<>  mv)

Sets the position of the observer (eye point).

Expressed in the local coordinate system (ex. of the owner ChBody, of ChAssetLevel,..)

void chrono::ChCamera::SetUpVector ( ChVector<>  mv)

Sets the position of the 'up' direction of the camera (default is vertical, VECT_Y) Expressed in the local coordinate system (ex.

of the owner ChBody, of ChAssetLevel,..)
