raster3d(1grass)

💖 raster3d 💖

okay bestie, you just pulled up raster3d from the GRASS User's Manual — yes, that's the manual name right there in the header, section 1grass, and it's literally the whole 3D raster command directory in one place. Think of it as the group chat where all your voxel besties live. 🧊✨

🌍 DESCRIPTION

So, the GRASS 8.5.0 Reference Manual starts with the whole vibe check on what GRASS even is:

Geographic Resources Analysis Support System, commonly referred to as GRASS, is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. 🔥

This reference manual — the one you're reading right now — details the use of modules distributed with Geographic Resources Analysis Support System (GRASS), an open source (GNU GPLed), image processing and geographic information system (GIS). Periodt. 💅

🧊 3D raster commands 🧊

okay so this is the main character list, every single one, no skips, no cap 👑

• r3.colors — Creates/modifies the color table associated with a 3D raster map. it's giving glow-up for your voxels 🌈
• r3.colors.out — Exports the color table associated with a 3D raster map. yeeting those colors out of GRASS 💌
• r3.cross.rast — Creates cross section 2D raster map from 3D raster map based on 2D elevation map. slicing that 3D situation into 2D 🍰
• r3.flow — Computes 3D flow lines and 3D flow accumulation. follow the flow, bestie 💧
• r3.gradient — Computes gradient of a 3D raster map and outputs gradient components as three 3D raster maps. three maps, one vibe ✨
• r3.gwflow — Numerical calculation program for transient, confined groundwater flow in three dimensions. aquifer math but make it 3D 🌊
• r3.in.ascii — Converts a 3D ASCII raster text file into a (binary) 3D raster map. glow-up from text to binary 💅
• r3.in.bin — Imports a binary raster file into a GRASS 3D raster map. come on in, binary 🫶
• r3.in.v5d — Import 3-dimensional Vis5D files. old-school format, still eating 🌪️
• r3.in.xyz — Create a 3D raster map from an assemblage of many coordinates using univariate statistics. so many points, so many numbers, one map 📍
• r3.info — Outputs basic information about a user-specified 3D raster map layer. the "who is she" of commands 👀
• r3.mapcalc — Raster map calculator. math but for rasters, iconic 🧮
• r3.mask — Establishes the current working 3D raster mask. masking the noise, protecting the peace 🎭
• r3.mkdspf — Creates a display file from an existing 3D raster map according to specified threshold levels. thresholds said slay 📊
• r3.neighbors — Makes each voxel value a function of the values assigned to the voxels around it, and stores new voxel values in an output 3D raster map. it's literally about who your voxel hangs out with 🫂
• r3.null — Explicitly create the 3D NULL-value bitmap file. committing to the void 💀
• r3.out.ascii — Converts a 3D raster map layer into a ASCII text file. binary → text, the reverse glow-up 📝
• r3.out.bin — Exports a GRASS 3D raster map to a binary array. bye bye in binary form 📦
• r3.out.netcdf — Export a 3D raster map as netCDF file. netCDF nation rise ☁️
• r3.out.v5d — Exports GRASS 3D raster map to 3-dimensional Vis5D file. reverse Vis5D pipeline, obsessed 🌪️
• r3.out.vtk — Converts 3D raster maps into the VTK-ASCII format. visualization ammo incoming 🎨
• r3.retile — Retiles an existing 3D raster map with user defined x, y and z tile size. chop it up on your terms ✂️
• r3.stats — Generates volume statistics for 3D raster maps. the numbers don't lie, fr fr 📈
• r3.support — Allows creation and/or modification of 3D raster map layer support files. the backstage crew of files 🎬
• r3.timestamp — Modifies a timestamp for a 3D raster map. giving your map a "when" 🕐
• r3.to.rast — Converts 3D raster maps to 2D raster maps. flattening the vibe, lovingly 💐
• r3.univar — Calculates univariate statistics from the non-null cells of a 3D raster map. nulls stay uninvited, stats stay winning 🏆

okay bestie that's the whole page 💖 huge thanks to © 2003-2026 GRASS Development Team for the copyright, and big love to the GRASS 8.5.0 Reference Manual — this was raster3d(1grass) on GRASS 8.5.0, and you ate by reading all of it. now go touch a voxel. 💅✨🎀
