v.out.pov 💖✨

okay bestie, welcome to the GRASS GIS User's Manual page for v.out.pov, and yes we are doing this, we are converting GRASS x,y,z points to POV-Ray x,z,y format. note the swappage. the axes get reordered. it's giving glow-up, it's giving coordinate remix 💅

NAME 🎀

v.out.pov — converts GRASS x,y,z points to POV-Ray x,z,y format.

KEYWORDS 🦋

vector, export, output

---

SYNOPSIS ✨

v.out.pov
v.out.pov --help
v.out.pov input=name  [layer=string]   [type=string[,string,...]]
output=name  [size=string]   [zmod=string]   [objmod=string]
[--overwrite]  [--help]  [--verbose]  [--quiet]  [--ui]

Flags 🫶

• --overwrite — allow output files to overwrite existing files. yes she will absolutely bulldoze what's already there, that's the whole point.
• --help — print usage summary. the lil "what do i even do" button.
• --verbose — verbose module output. she talks more. love that for her.
• --quiet — quiet module output. she shuts up. also valid.
• --ui — force launching GUI dialog. for when you want the pretty window instead of the terminal grind.

Parameters 🌸

• input=name [required] — name of input vector map. or, plot twist, a data source for direct OGR access.
• layer=string — layer number or name ('-1' for all layers). a single vector map can be connected to multiple database tables, and this number determines which table to use. when you're doing direct OGR access, this is the layer name instead. default: -1.
• type=string[,string,...] — input feature type. options: point, line, boundary, centroid, area, face, kernel. default: point,line,area,face.
• output=name [required] — name for output POV file.
• size=string — radius of sphere for points and tube for lines. may be also variable, e.g. grass_r. default: 10.
• zmod=string — this string is appended to each z coordinate. examples: '*10', '+1000', '*10+100', '*exaggeration'.
• objmod=string — object modifier (OBJECT_MODIFIER in POV-Ray documentation). example: "pigment { color red 0 green 1 blue 0 }".

DESCRIPTION 💜

v.out.pov converts GRASS vector data to POV-Ray format (www.povray.com). that's it, that's the whole job, and she does it flawlessly no cap 🔥

---

EXAMPLE 🍓

v.out.pov input=vector3d output=vector3d.pov objmod="pigment { color red 0 green 1 blue 0 }"

the generated file can be included in an existing .pov file with the following statement:

#include "vector3d.pov"

like, you literally just drop that line in and the whole thing shows up. iconic behavior honestly 👑
