A program for viewing 3D models from .obj files
Created with Qt + OpenGL, QtGifImage is taken from here
- Qt6.2.4 + QtOpenGLWidgets + OpenGL
- g++
- Make and CMake
- Download the repository
- cd to src folder
- Type
make install - Go to Desktop and run program 3DViewer 2.1
Go to src folder and type make uninstall or just delete app icon
- To open a *.obj file, go to File -> Open or Press ⌘1 and open the desired file.
- To close a file, go to the tab File -> Close or Press ⌘2 and the object will be deleted.
- To see information about the object, you need to go to the tab File -> Info or Press I, after which the information about the current object will be displayed.
- To hide the settings window, go to Settings -> Hide/Show or Press ⌘3, then the settings window will be closed or opened if it was closed.
- To change the projection type, go to Settings -> (Press O)Orthographic/Perspective(Press P), then the projection type will be changed.
- To make a screenshot, go to the Create -> Image tab, then select the format of the screenshot and save it.
- To make a gif-animation, you need to go to the tab Create -> GIF, after which the main window shows a red frame, indicating that the recording is in progress. After 5 seconds, the recording will be saved(10fps).
- To set the color of the lines, click the Set Lines Color button and select the desired color.
- To change the thickness of the lines, move the Line Width slider to the right to increase and to the left to decrease.
- To draw a line with dashed lines, click the Dashed button, and to draw a solid line, click the Solid button.
- To change the color of the vertices, click the Set Vertex Color button and select the desired color.
- To change the size of the vertices, slide the Vertex Size slider to the right to increase and to the left to decrease.
- To remove the display of vertices, click the None button.
- To draw the vertices as a circle, click the Circle button.
- To draw the vertices as a square, click the Square button.
- To rotate the figure relative to the X, Y, Z axes, hover over the desired coordinate in the Rotate section and change it with the mouse wheel.
- To move the figure relative to the X, Y, Z axes, hover over the desired coordinate in the Move section and change it with the mouse wheel.
- To resize the shape, move the Scale slider to the right to zoom in, or hover the mouse over the spinbox to zoom out.
- To change the background color, click the Set Background Color button, select the desired color, and then the background will change.
- To use light, first load the model with normals(vn), enable it in Settings -> Light (on by default), change the projection type to non-wireframe if the Light button is dimmed, than your model does not support light.
- You can change the projection of the light: press Flat Shading for the average polygon color or Smooth Shading to enable interpolation.
- You can always return to wireframe mode by simply pressing the Wireframe button.
- You can change the position of the light source in X, Y, Z coordinates, just enter a new position or change it with the mouse wheel.
- You can change the light intensity with R, G, B, just enter a new value(0.1 - 1.0) for each component or change it with the mouse wheel.
- To load a texture on a model, first, it must have texture coordinates (vt), if there are, press the Apply texture button and select the .bmp image, otherwise your model does not support texture mapping.
- To unload a texture, click Unload Texture, it will be removed from memory.
- If you change the display type to wireframe, with loaded texture, the texture will also be removed.
- You can save the UV-Map, the image should be on the texture at this point, click the Save UV-Map button and select a save location.
