Detailed Description

A view on the isometric world.

Can be used to render a specific portion of an isoWorld onto a particular part of the screen.

The axes are aligned like this +y | ./+z | ./ | ./ |/ \. \. \. \+x

Member Function Documentation

virtual void iIsoView::Draw (    )  [pure virtual]

draw the view onto the screen. Call this when in 3d mode (with the engine->getBeginDrawFlags passed)

virtual iIsoEngine* iIsoView::GetEngine (    )  const [pure virtual]

Get the iso engine this view belongs to.

virtual iCamera* iIsoView::GetFakeCamera (  const csVector3 &    center, iIsoRenderView *    rview )  [pure virtual]

Return a fake iCamera implementation, that approximates isometric near the given position (in world space). The renderview is also used. This is a very partial implementation of iCamera. For Internal Use!

virtual const csRect& iIsoView::GetRect (    )  const [pure virtual]

Get the rectangle on the screen to draw to.

virtual const csVector2& iIsoView::GetScroll (    )  const [pure virtual]

See the screen position scrolled to.

virtual csVector3 iIsoView::GetViewScroll (    )  const [pure virtual]

See the world position scrolled to (as shown in center of viewport).

virtual iIsoWorld* iIsoView::GetWorld (    )  const [pure virtual]

Get world shown in view.

virtual void iIsoView::MoveScroll (  const csVector3 &    delta )  [pure virtual]

Move the scroll position by delta (in world space).

virtual void iIsoView::S2W (  const csVector2 &    screen, csVector3 &    world )  const [pure virtual]

Transform screen coordinate into a world space coordinate. The world space coordinate will have y=0.

virtual void iIsoView::SetAxes (  float    xscale, float    yscale, float    zscale, float    zskew, float    xskew )  [pure virtual]

set the axis of the view on the world. The scale is in pixels, and must be > 0. Default is g3d->height/16. The skew values determine the angle of the z and x axis. it is the amount of vertical change per horizontal change. 1.0 gives perfect isometrical view, 0.5 flattens the lines. skew values must be > 0. For a nice y scale, (sqrt(xskew*xskew+1+sqrt(yskew*yskew+1)/2 can compensate for the lengthening and shortening of the axes due to the skewing.

virtual void iIsoView::SetRect (  const csRect &    rect )  [pure virtual]

Set the rectangle on the screen to draw to.

virtual void iIsoView::SetScroll (  const csVector3 &    worldpos, const csVector2 &    coord )  [pure virtual]

Set the scroll position. Show world space pos as screen space coord.

virtual void iIsoView::SetWorld (  iIsoWorld *    world )  [pure virtual]

Set world to use.

virtual void iIsoView::W2S (  const csVector3 &    world, csVector3 &    screen )  const [pure virtual]

Transform world space coordinate into a screen coordinate. The returned z value can be used for a zbuffer, is bigger when further away.

virtual void iIsoView::W2S (  const csVector3 &    world, csVector2 &    screen )  const [pure virtual]

Transform world space coordinate into a screen coordinate.
