mesh{ } - Netz (mesh) aus triangle-Dreiecken oder smooth_triangles-Dreiecken
Dies benötigt mindestens die Angabe der Scheitelpunkte (vertex) / Eckpunkte der Dreiecke.
built-in shape, non-CSG |
Einfaches triangle mesh:
//Syntax: --------------------
mesh {
triangle{vertex_1}
triangle{vertex_2}
//...
triangle{vertex_3}
// Option für uv_mapped texture:
uv_vectors
<uv_Corner_1>,
<uv_Corner_2>,
<uv_Corner_3>
// ---------
} //------------------------- |
|
//optional zuvor deklarierten Texturen :
mesh {
triangle{vertex_1 texture{Texture_1}}
triangle{vertex_2 texture{Texture_2}}
//...
triangle{vertex_3 texture{Texture_3}}
} //---------------------------------- |
Smooth_triangle_mesh mit Oberflächen-Normalenvektoren:
//Syntax: -----------------------------------------------------------------
mesh {
smooth_triangle{vertex_1, normal_1, vertex_2, normal_2, vertex_3, normal_3}
//...
smooth_triangle{vertex_1, normal_1, vertex_2, normal_2, vertex_3, normal_3}
} //---------------------------------------------------------------------- |
Beispiel 1:
mesh {
triangle{<0.20, 0, 0.55>,<0.25, 0, 0.17>,<0.00, 0, 0.00>}
triangle{<0.65, 0, 0.50>,<0.50, 0, 0.15>,<0.00, 0, 0.00>}
triangle{<0.50, 0, 0.15>,<0.00, 0, 0.00>,<0.50, 0,-0.15>}
triangle{<0.50, 0, 0.15>,<0.50, 0,-0.15>,<1.00, 0, 0.00>}
triangle{<0.00, 0, 0.00>,<0.50, 0,-0.15>,<0.65, 0,-0.50>}
triangle{<0.25, 0,-0.52>,<0.25, 0,-0.17>,<0.00, 0, 0.00>}
texture{ pigment{ color rgb<0.0,1.0,0.0>}}
} //---------------------------------------- |

Gebrauch mit z.B. POV-Tree + TOM_TREE.

Beispiel 2: // Hinweis: Die Texture müssen vor dem Parsen des Netzes(mesh) deklariert werden!
#declare T_1 = texture{ pigment{ color rgb<0.2,0.5,0.0>}}
#declare T_2 = texture{ pigment{ color rgb<0.0,1.0,0.2>}}
#declare T_3 = texture{ pigment{ color rgb<0.0,0.5,0.0>}}
#declare T_4 = texture{ pigment{ color rgb<0.2,0.9,0.0>}}
mesh {
triangle{<0.20, 0, 0.55>,<0.25, 0, 0.17>,<0.00, 0, 0.00> texture{T_1}}
triangle{<0.65, 0, 0.50>,<0.50, 0, 0.15>,<0.00, 0, 0.00> texture{T_2}}
triangle{<0.50, 0, 0.15>,<0.00, 0, 0.00>,<0.50, 0,-0.15> texture{T_4}}
triangle{<0.50, 0, 0.15>,<0.50, 0,-0.15>,<1.00, 0, 0.00> texture{T_3}}
triangle{<0.00, 0, 0.00>,<0.50, 0,-0.15>,<0.65, 0,-0.50> texture{T_2}}
triangle{<0.25, 0,-0.52>,<0.25, 0,-0.17>,<0.00, 0, 0.00> texture{T_1}}
rotate<0,0,10>
