FUNCTION

Controls the drawing surface for models and objects.
Parameters that can be set are as follows.

NJD_CONTROL_3D_DISP_AXIS
Draws axes (1 long) at the origin for each model.
X axis:blue, Y axis:green, Z axis:red
NJD_CONTROL_3D_NO_CLIP_CHECK
Specifies not to perform clipping check when drawing models.
With this parameter set, drawing efficiency will be up if model drawing is within a screen completely.
NJD_CONTROL_3D_CONSTANT_ATTR
Allows to change model attribute. Changing parameters should be specified with njSetConstantAttr().

NJD_CONTROL_3D_CONSTANT_MATERIAL
Changes material data of models to fixed value. Changing parameters should be specified with njSetConstantMaterial().

NJD_CONTROL_3D_OFFSET_MATERIAL
Supplements material data of models. Supplementing parameters should be specified with njSetConstantMaterial().

NJD_CONTROL_3D_DEPTH_QUEUE
Validates depth queue. Depth queue here means to change degree of transparency accommodating with distance.
Depth queue parameters should be specified with njSetDepthQueue().
NJD_CONTROL_3D_VERTEX_OFFSET
Moves vertex data in normal line direction.
The offset to move is specified by _nj_vertex_offset_ variable.
NJD_CONTROL_3D_MODEL_CLIP
Validates clipping by model.
NJD_CONTROL_3D_CONSTANT_TEXTURE_MATERIAL
Makes texture material color white.
In default, it uses material color.

EXAMPLE

njInitSystem( NJD_RESOLUTION_VGA, NJD_FRAMEBUFFER_MODE_RGB565, 1 );
njInitMatrix( matrix, 128 );
njInit3D( vbuf, 4096 );
njInitView( &view );
njCreateLight( &light, NJD_DIR_LIGHT );
njSetView( &view );

njControl3D( NJD_CONTROL_3D_NO_CLIP_CHECK | NJD_CONTROL_3D_DISP_AXIS );

while(1) {
  njClearMatrix();
  njTranslate( NULL, 0.f, 0.f, -10.f );
  njRotateXYZ( NULL, xx,yy,zz );
  njDrawObject( object );
  xx += 257;
  yy += 179;
  zz += 193;
  njWaitVSync();
}
