ccbl

Displays an object using the primitive color.

Set the Combine mode to PRIMITIVE.(*)

[RDP]->CL_COMBINE->COMBINE_MODE->CYCLE1: PRIMITIVE

Try changing the primitive color and see the results.

[RDP]->CL_COMBINE->PRIM_COLOR

Applies a texel color unchanged.

Sets to a display with writing.

Set the Geometry mode.

The Combine mode setting is as follows.(*)

[RDP]->CL_COMBINE->COMBINE_MODE->CYCLE1: DECALRGB

Uses reflection mapping to simulate specular highlighting.

TORUS2 is used as the model so that the effect is readily seen.

Select IA8 HIGHLIGHT for the texture.

The Geometry mode settings used are the same as for reflection mapping.(*)

Because reflection mapping is used, the light is assumed be located at the viewpoint. Thus, only DIF1 is used.

Light color settings are as follows.(*)

+[LIGHT COLOR]--+        
|      R  G  B  |        
|DIF1: 50 50>00<|

|DIF5: 00 00 00 |        
|DIF6: 00 00 00 |        
|DIF7: 00 00 00 |

+---------------+        

The Combine mode setting is as follows.(*)

[RDP]->CL_COMBINE->COMBINE_MODE->CYCLE1: HILIGHTRGB

The primitive color is set to the same color as the light color.(*)

+[PRIM COL]-+           
| RED  : FF |           
| GREEN: FF |

+-----------+           

The primitive color becomes the light color.

Uses Fog.

Set the Geometry mode.

The cycle type is set to 2 cycles.(*)

[RDP]->CYCLE_TYPE->G_CYC_2CYCLE

To make the effect readily visible, select DECALRGB as the Combine mode, CUBE as the model, and BRICK as the texture. In addition, specify the following Combine node settings.

[RDP]->CL_COMBINE->COMBINE_MODE->CYCLE1: DECALRGB
[RDP]->CL_COMBINE->COMBINE_MODE->CYCLE1: PASS2

Set the Rendering mode.(*)

[RDP]->BLENDER->RENDER_MODE->CYCLE1: FOG_SHADE_A
[RDP]->BLENDER->RENDER_MODE->CYCLE2: AA_ZB_OPA_SURF2

Select the Fog color.(*)

[RDP]->BLENDER->FOG_COLOR settings are as follows.

+[FOG COL]--+            
|<RED  > 80 |            
| GREEN: 80 |            
| BLUE : 80 |            
| ALPHA: 80 |            
+-----------+            

Set the BG color to a color close to that of the Fog.

[MISC]->BG_COLOR->GLAY

The positions of the Fog threshold and Fog color saturation can be changed by changing the Fog position ([RSP]->FOG_POS).

Set the cycle type to 2 cycles.(*)

[RDP]->CYCLE_TYPE->G_CYC_2CYCLE

Set the Combine mode.(*)

[RDP]->CL_COMBINE->COMBINE_MODE->CYCLE1: TRILERP
[RDP]->CL_COMBINE->COMBINE_MODE->CYCLE1: DECALRGB2

Set the Rendering mode.(*)

[RDP]->BLENDER->RENDER_MODE->CYCLE1: PASS
[RDP]->BLENDER->RENDER_MODE->CYCLE2: AA_ZB_OPA_SURF2

Set the texture.(*)

[MISC]->TEXTURE->RGBA16 BRICK_MM

Anti-aliasing in N64 is ultimately performed by VI. Blender writes the anti-aliasing data (cover values) to the frame buffer when it writes the pixel values to that buffer.

Using the G_RM_VISCVG, ccbl enables cover values to be visualized. Try changing the Blender settings and using this feature to see the types of cover values generated. The result will likely be many very interesting discoveries.

Combine mode is set as follows.(*)

[RDP]->CL_COMBINE->COMBINE_MODE->CYCLE1: PRIM

The model and texture are set as follows.

[MISC]->MODEL->CUBE
[MISC]->TEXTURE->RGBA16 TREE

Combine mode is set as follows.(*)

[RDP]->CL_COMBINE->COMBINE_MODE->CYCLE1: DECALRGBA

Rendering mode is set as follows.(*)

[RDP]->BLENDER->RENDER_MODE->CYCLE1: AA_ZB_TEX_EDGE

The model is set as follows.(*)

[MISC]->MODEL->TRIANGLE

The model is set as follows.(*)

[RDP]->BLENDER->RENDER_MODE->CYCLE1: AA_ZB_OPA_DECAL

The BG model is set as follows.(*)

[MISC]->BG_MODEL->PLANE

The model is set as follows.(*)

[MISC]->MODEL->TETRA

Rendering mode is set as follows.(*)

[RDP]->BLENDER->RENDER_MODE->CYCLE1: AA_ZB_OPA_INTER

The BG model is set as follows.(*)

[MISC]->BG_MODEL->PLANE

The BG model is set as follows.

Rendering mode is set as follows.(*)

[RDP]->BLENDER->RENDER_MODE->CYCLE1: AA_ZB_PCL_SURF

Alpha comparison is set as follows.(*)

[RDP]->BLENDER->CD AD AC->G_AC_DITHER

A common bug is to set the alpha comparison after the rendering mode, so that even if G_RM_*_PCL_SURF is specified as the rendering mode, it is subsequently overwritten with the alpha comparison setting.
