ASL Scripts / Fast 3D Export (Beta) 0625
« on: May 10, 2020, 12:13:00 pm »
Here is an export plugin for Fast3D at source level.


Debug mode is enabled

ver 20200625 (Beta)
 
 
 
  Features:
  • Duplicate Vertex removal
  • Triangle Sorting
  • Flat Shading
  • Smooth Shading (Lighting only, An8 does not support Vertex Shading)
  • Lighting
  • Fog (Disables Vertex Alpha as N64 places Distance on Vertex Alpha)
  • Texture Mapping
  • Environment Mapping
  • Bounding Box 
  • Bounding Volume Radius - Nothing Output Yet
  • Binary Seperating Plane (Partial Support with Tree traversal)
  • Groups and full hiearchy. Usefull for animation or part culling.   [/color]

 
  Supports:
  • Fast3D (16 vertex cache)(Default)
  • 4Tri   (GE/PD Fast3D Extension) 
  • F3DEX  (32 Vertex Cache, 2Triangles)
  • F3DEX2 (32 Vertex Cache, 2Triangles)   

  WishList:
  Portals (use mesh name "PortalA-B")
  Animations - Translate/Rotate
                        Needs flag IsAnimate else Pre-Calc matrix
                        using $point = $transformMat.Project($point);

Ongoing Anim8or Development / ASL issues
« on: May 05, 2020, 09:46:24 pm »
ASL Bugs and Feature requests as of Build 1379

Nested If statements cannot return to caller, an8 hangs, turns white, titlebar states (Not Responding) and console stops output.
Code: [Select]
// Return True if Vertex Exists, Save NewID Mapping to $gVtxIDMap
int $VertexExists(point3 $xyz, string $uv, point3 $rgb, int $a)
{
int $i, $r;

for ($i = 0; $i < $gXYZs.size; $i++)
{
$DebugPrint(PrintToString("Compare to %d", $i));
// cant do && "Illegal Type arg"
if (($xyz.x == $gXYZs[$i].x) && ($xyz.y == $gXYZs[$i].y) && ($xyz.z == $gXYZs[$i].z))
{
if ($uv == $gSTs[$i])
{
if (($rgb.x == $gRGBs[$i].x) && ($rgb.y == $gRGBs[$i].y) && ($rgb.z == $gRGBs[$i].z))
{
if ($a == $gAs[$i])
{
$gVtxIDMap[$gVtxIDMap.size - 1] = $i;
//return true;
$r = 1; //BUG cannot return from here, this makes script wasteful
}
}
}
}
}
return $r;
}
Attributes cannot return NULL...
workaround: Use a global Attribute and use Push/Size = 0
Code: [Select]
//return $gCurObject.GetAttribute($i);
$gLookupAttributeUcase.push($gCurObject.GetAttribute($i));
return;
}
}
//return NULL;
$gLookupAttributeUcase.size = 0;
}

As Documented already Recursion is not supported, however it would be good to support for parsing trees.
Code: [Select]
void $ParseChildren(shape $Shape)
{
...
$DebugPrint("Parsing Children " + $Shape.name);

if ($Shape.GetKind() == SHAPE_KIND_GROUP)
{
//Recursion Not Supported
$ConsolePrint("Groups are not supported\n");
//$ParseChildren($Shape);
}
...
}

I also put together some functions for people to use but hope for native support for them instead.
Code: [Select]
// Returns Index to start of $Contains if within $Base.
// Returns False if $Base does not contain $Contains
int $StringContains(string $Base, string $Contains)
{
int $i, $r;
string $Comparitor;
//$DebugPrint(PrintToString("looking for %s in %s", $Contains, $Base));
for ($i = 0; $i < max(0,($Base.length - $Contains.length)); $i++)
{
$Comparitor = $Base.SubString($i, ($i + ($Contains.length-1)));
$DebugPrint(PrintToString("contains %s at %d", $Comparitor, $i));
if ($Comparitor == $Contains)
{
$r = $i +1;
break;
}
}
//$DebugPrint(PrintToString("returning %d", $r));

return $r;
}

// Split String $Base anywhere $Split occurs
// Returns Array (via $gSplit) of Strings
int $StringSplit(string $Base, string $Split)
{
int $r, $Start, $End;
$gSplit.size = 0;
while (1)//$StringContains($Base.SubString($Start, $Base.length), $Split))
{
$End = $StringContains($Base.SubString($Start, $Base.length), $Split);

if (!$End)
{
//$r = 0;
$DebugPrint($Base.SubString($Start, $Base.length));
$gSplit.push($Base.SubString($Start, $Base.length));
break;
}
$r++;

$DebugPrint($Base.SubString($Start, $End - 1 - $Split.length));
$gSplit.push($Base.SubString($Start, $End - 1 - $Split.length));
$Start = $Start + ($End-1) + ($Split.length);
}
$DebugPrint(PrintToString("Split legnth %d, contains %s", $gSplit.size, $gSplit[$gSplit.size-1]));
return $r;
}

// Returns String from Array (via $gSplit) of Strings
string $StringJoin()
{

for($i=0; $i< $gSplit.size; $i++)

}
$gSplit.size = 0;
return $t;
}

//Cast To Integer
int $int(float $val)

}

//Cast to Float
float $float(int $val)

}


I also took the documentation and put it in a h file for use in VS.
I shifted the comments round so it works with Intellisense and word completion as you type.

Which reminds me, any chance of ignoring #include "a8s.h" and then including other script files?
Also #if(0) #endif would be good to block certain code blocks from functioning

Many Thanks

Finished Works and Works in Progress / Diffuse Inter-Reflection Test
« on: October 23, 2017, 11:18:14 am »
I was in the process of making a lighting tutorial for PerfectGold when I wanted some comparison shots from An8.
Ive mentioned in the past about ART needing Diffuse Inter-Reflection and ToneMapper but I simulated it with Glossyreflector.

My material settings are crazy
Ambient 0
Diffuse 20 + texture
Specular 0.95 + Texture
Roughness 0

Setting specular to 1 means diffuse doesn't work

Scene Lighting set to 1 for exterior, 4 for interior

Im quite sure these would be much better (not to mention easier to set up) if an8 suported it as a checkbox
Also note that Ambient Occlude is NOT on, AmbOcc is a simplified DIR.

The results

Ongoing Anim8or Development / Problem with Local Lights
« on: March 03, 2015, 07:34:26 am »
well, they just dont give any light. Everything is black unless an infinit or spot light is added.

This is in raytracing mode, not scanline.

Oh... Odd... now Im testing its working again... ok... so, it must be the polycount that makes it fail.
Both previous times I tried I had high polycounts and they refused to light anything. I ckecked the face-oriantation but that didnt help.

OHHH! I found the bug.

Local Lights only work in camera mode.

Just going to test that in a new project by adding just 1 light.
Ok, definatly confirmed, local lights only work in camera, not ortho or perspective.
