Sandy engine learning notes: multi-dimensional textures

 

In the sandy engine, we can map multiple dimensions. The box class is a typical example. It can perform multi-faceted textures and different Paster effects on the six faces. The procedure is very simple. You can select different surfaces only when presenting the surface, give different surfaces such a simple effect.

 

There is a getface method in the box class, which can return the primitiveface type. This type contains an appearance attribute. Using this attribute, we can assign different methods.

Appearance: appearance

Getface (p_nface: uint): primitiveface returns a primitiveface object (an array of polygons) Defining the specified face. simple process: Embed several images in flash and process bitmap as links. Here we only use the image for demonstration and change it to face1 --- face5 for different faces, first, we need to do some simple processing. Prepare multiple textures as follows: Private var skin1: bitmapdata = new face1 (); var Material1: bitmapmaterial = new bitmapmaterial (skin1); var app1: appearance = new appearance (Material1); // create a material surface box for the object. getface (0 ). appearance = app1 ;// Specify the material surface ...... the method is the same. In this way, we can create different textures for the box at http://blog.5d.cn/user45/hero82748274/category/148744.htmlcode labels: Package <br/> {<br/> Import flash. display. sprite; <br/> Import flash. events. *; <br/> Import Sandy. core. scene3d; <br/> Import Sandy. core. scenegraph. *; <br/> Import Sandy. primitive. *; <br/> Import Sandy. core. data. *; <br/> Import Sandy. materials. *; <br/> Import Sandy. materials. attributes. *; <br/> Import Sandy. core. scenegraph. mode7. *; <br/> Import flash.
