💖 ctmviewer 💖

okay bestie, so this is ctmviewer(1) from the General Commands Manual, and it's literally a 3D viewer, like, for models. various file formats. she contains multitudes. let's get into it 🦋

✨ NAME ✨

ctmviewer — a 3D viewer for models of various file formats 👑

---

🌸 SYNOPSIS 🌸

ctmviewer [modelfile [texturefile]]

---

🎀 DESCRIPTION 🎀

so ctmviewer is a 3D file viewer that can load, show and save 3D model files in several different formats. no cap. she does it all.

the program displays an interactive 3D view of the model, which you can operate with the mouse — like, for rotating and zooming, the classic stuff. it's giving main character energy honestly.

if the model file you picked contains texture coordinate information, you can also specify which 2D image file to use as a texture with the extra texturefile argument. and if no texture file is given — whether by the 3D model file itself, or by the texturefile argument — then a standard 2D grid gets used as the texture instead. fallback queen 💅

🫶 GUI OPERATIONS 🫶

besides the command line arguments, ctmviewer offers a bunch of operations you can do straight from the 3D GUI display. and for help? just press the F1 key. she tells you everything 🧚

💜 Loading and Saving

you can load and save 3D model files from the program either by using the buttons in the upper left corner of the 3D display, or by using the keyboard shortcuts CTRL+O (open) and CTRL+S (save). pick your fighter, both slay.

you can also load a texture file from the program by using the Open Texture button. periodt.

💜 Rendering

to toggle between a normal filled surface view (default) and a wire frame view, press the w key. the way that's literally one keypress 😭

💜 Camera Control

• hold down the left mouse button and move the mouse → the camera rotates around the 3D model.
• hold down the right mouse button and move the mouse → the camera will pan left/right and up/down.
• hold down the middle mouse button and move the mouse → the camera will zoom in and out. you can also use the mouse wheel (ngl, not supported on all systems 🙈) or the +/- keys to zoom in and out.
• double click the left mouse button on a point on the model → focuses the camera on that point. so specific. so iconic.
• press the f key → fit the model into the screen view (re-center and re-zoom). the glow-up button fr fr.
• press the y key → changes the camera up direction to the Y axis. this may be necessary if the model was designed in or for an environment where the Y axis is considered the up direction. iykyk.
• press the z key → changes the camera up direction to the Z axis (this is the default).

🌈 FILE FORMATS 🌈

the following 3D model file formats are supported:

• OpenCTM (.ctm)
• Stanford triangle format (.ply)
• Stereolitography (.stl)
• 3D Studio (.3ds)
• COLLADA 1.4/1.5 (.dae)
• Wavefront geometry file (.obj)
• LightWave object (.lwo)
• Geomview object file format (.off)
• VRML 2.0 — export only (.wrl)

the following 2D image file formats are supported (as texture):

• JPEG (.jpg)
• PNG (.png)

⭐ AVAILABILITY ⭐

ctmviewer is designed to be portable, and is available for several different systems, including (but not limited to): Windows, Mac OS X (10.3+), Linux and OpenSolaris. she travels 💅✨

ctmviewer uses OpenGL for its accelerated 3D display. when the OpenGL implementation supports it, ctmviewer will use per pixel Phong shading for improved visual appearance. otherwise ctmviewer will fall back to classic per vertex shading. either way she's cute, but one of them is glowing 🔥

lowkey obsessed with how much this little viewer can do. go forth and rotate some models, bestie 🦋💖

and that's the whole page!! this was ctmviewer(1) from the General Commands Manual — the footer doesn't have any version or date info on it, so like, that's the vibe check, no extra deets to spill. byeee 👑✨
