TypeSafeSchwalbe / NanoCAD

A simple, text based 3D modeling program for low-poly models.

NanoCAD is a simple, text based 3D modeling program for low-poly models that is able to load, edit and save any .obj-file.

NanoCAD is entirely text-based. You never need to touch your mouse to edit a model.
The goal with NanoCAD was to create something that is easy to learn and simple to use.

Commands

Meanings:

• <mesh-id> - The index of any mesh or it's alias.
• <vertex-id> - The index of any vertex in the previously mentioned mesh.
• <alias> <new-mesh-alias> - Name to give to a mesh. May then be used instead of an index when asked for a <mesh-id>.
• (...) - Optional parameter.
• <... ("..."/"..."/"...")> - Value may be one of the values in parentheses, without quotation.

Commands:

• help - Shows a list of all possible commands.
• vinfo/vi - Toggles the visibility of detailed vertex information, showing position and texture mapping for each vertex. Disabled by default.
• normals/nor - Toggles the visibility of surface normals and their mesh indices. Disabled by default.
• scroll/scr/s <mesh-id> - Scrolls the mesh data view (top left) to have the given mesh in the center. The mouse wheel can also be used to scroll.
• new/nw <vertex-count ("3"/"4")> (<new-mesh-alias>) - Creates a new mesh. When passing 3 for <vertex-count>, a triangle is created. When passing 4 for <vertex-count>, a quad is created. The new mesh gets the given alias, when one is passed to <new-mesh-alias>.
• alias/al <mesh-id> (<alias>) - Sets the alias of the given mesh to a new one. When nothing is passed to <alias>, the alias gets removed from the mesh.
• look/lk <mesh-id> (<vertex-id>) - Sets the camera to always look at the center given mesh (or a specific vertex, if passed) until the [ENTER]-key is pressed or a new command is entered.
• edit/ed <mesh-id> <vertex-id> <pos-x/"_"> <pos-y/"_"> <pos-z/"_"> <tex-mapping-x/"_"> <tex-mapping-y/"_"> - Edits the raw data of a given vertex. When _ is entered as a parameter (except in <mesh-id> and <vertex-id>), the value is not modified.
• move/mv <mesh-id> <step-size> - Enters move mode for the given mesh (until [ENTER] is pressed or a new command is entered), where the given mesh can be moved using the arrow keys. Pressing [0]..[9] moves that vertex only, while pressing [A] moves the entire mesh again. Pressing [X], [Y] or [Z] moves it along that axis. Pressing [ARROW_UP] or [ARROW_RIGHT] adds the value of <step-size> to the position value for the selected axis, while pressing [ARROW_DOWN] or [ARROW_LEFT] subtracts the value. The index of each vertex is also displayed while the command is active.
• uv <mesh-id> - Enters uv mode for the given mesh (until [ENTER] is pressed or a new command is entered), where the texture mappings of the vertices of the given mesh can be modified using the arrow keys. Pressing [0]..[9] selectes a specific vertex. Pressing [ARROW_UP] subtracts 1 from the texture mapping value for y of the selected vertex. Pressing [ARROW_DOWN] adds 1 to the texture mapping value for y of the selected vertex. Pressing [ARROW_LEFT] subtracts 1 from the texture mapping value for x of the selected vertex. Pressing [ARROW_RIGHT] adds 1 to the texture mapping value for x of the selected vertex. The index and texture mappings of each vertex are also displayed while the command is active.
• invnor/inor <mesh-id> - Inverts the surface normal vector of a given mesh by inverting the order of all vertices in the mesh.
• copy/cp <mesh-id> (<new-mesh-alias>) - Creates a copy of the given mesh. The new mesh gets the given alias, when one is passed to <new-mesh-alias>.
• remove/rem/rm <mesh-id> - Deletes a given mesh.
• clear - Deletes all meshes.
• load/ld <model-name> - Loads the model from the .obj-file at /files/<model-name>.obj, where the path root is the installation directory.
• save/sv <model-name> - Saves the model and a material file to /files/<model-name>.obj and /files/<model-name>.mtl, where the path root is the installation directory. The material file points to <model-name>.png, so the current texture at /res/texture.png should be copied next to the model files and renamed to <model-name>.obj before using the model.
• texture/tex - Reloads the texture from /res/texture.png, where the path root is the installation directory. When loading a model, the texture should be loaded BEFORE loading the model file using load or ld.

RoseQuartz

NanoCAD was made using RoseQuartz, and exported models are also fully supported by the engine.
