this is a 3d engin named our_3d_engin.
our_3d_engin feature:
1:there is no float.
2:it do the 3d things all by softwear.
3:base on 1 and 2 , it can execution on arm which have no 3d hardwear accelerate.

08-0826-1640
添加了 cmp_z in obj
//-----------------------------------------------------------
08-0826-1040
添加了 clip-bmp,clip-groud,clip-flat
//-----------------------------------------------------------
08-0819-1640
更改了 sin—cos—table，可以改变精度
//-----------------------------------------------------------
//-----------------------------------------------------------
08-0819-1040
更改MATERIAL的emn，增加了 好几个选项，并实现功能，下次添加，一个三角形每个点对应一个颜色。
//-----------------------------------------------------------

添加了一个点对应一个颜色。下次添加，一个三角形每个点对应一个颜色。
//-----------------------------------------------------------
08-0818-1701
ojb结构添加clor ，和clor_work，去掉tran结构里的clor and clor_work,这样可以减少内存
特别在用MATERIAL_point
//-----------------------------------------------------------
080422
使obj的变化可以更多
//-----------------------------------------------------------
080417
添加了点光源,平行光,环境光,obj_init,lit_init
添加了除函数,但是效率不高
//-----------------------------------------------------------
//-----------------------------------------------------------
080410
可以移植到ads编译了,并测了一些函数的时间,添加了一个光源
//-----------------------------------------------------------
//-----------------------------------------------------------
080409
很久没有写了，今天再看看有什么可以做的,整理了一下
