Class TAdRenderingSurface

Creates an instance of TAdRenderingSurface. Remember that TAdRenderingSurface is an abstract class, that should not be created directly. Use TAdDraw or TAdTextureSurface instead.

Destroys the instance of TAdRenderingSurface.

Clears the surface using a 24 Bit color. You may use the color constants provided by Delphi/Lazarus or the 24 Bit color constants in the AdConsts unit or use the RGB function from the unit AdTypes. This function clears the color buffer, the stencil buffer (clear value 0) and the Z-Buffer (clear value 1).

Clears the surface using a 32 Andorra color value. You may use the color constants from the unit AdConsts or the Ad_ARGB function. If your using a transparent value when clearing a rendering surface, the surface is filled with that transparent color so that you may draw it over other objects. This function clears the color buffer, the stencil buffer (clear value 0) and the Z-Buffer (clear value 1).

Calls Scene.Setup2DScene with the width and the height of the surface. The viewport is changed, so that it covers the whole screen. After calling Setup2DScene the relative and the absolute coordinate system are equal.

A hardware accelerated canvas. All drawing operations will automatically be made on the owner of the canvas property.

This is the place where the scene settings for the surface are made.

Simple class that copes with scene management.

Options that control the rendering process. When TAdRenderingSurface is created, the options are copied from the parent TAdDraw.

DisplayRect returns the size of the current szene. Those coordinates are relative.

The width of the surface in pixels. Absolute coordinates. Use the scene property to get the relative width of the surface.

The height of the surface in pixels. Absolure coordinates. Use the scene property to get the relative height of the surface.
