Posted May 6, 2020 hello all, For a school project i am creating a 3D object viewer using OpenGL, what features would you consider to be key for such a project? Any responses would be appreciated. -matty If you judge a fish based on its ability to climb trees it will go its whole life thinking its a failure.

Posted May 6, 2020 - Being able to rotate the model would be nice - A panel with some info on the 3D model (filename, location, amount of vetexes/polygons, size, etc.) - buttons to quickly look at the object from the top/bottom/left/right would be nice to have - Turn on/off a light - Render modes which show the edges of the vertexes/polygons - 'Proxy mode' (basically a way to render a simplification/low 'res' version of the file to render quickly). Those are some of the things I would want to have in a 3D model viewer. Probably ranged from 'easily added/necessary features' to 'cool to have/great to show off your prowess as a programmer'.

Posted May 6, 2020 Author Do you have any ideas when it comes to shaders/lighting effects? If you judge a fish based on its ability to climb trees it will go its whole life thinking its a failure.

Posted May 7, 2020 That's a large project for school work. Just getting the polygons display properly is a huge task. If a triangle is half behind another one you need to only draw it partially and the Z order won't help you. That being said the easier to implement and can be tweaked alot is the post processing part. Anything, anti-alias, super scale, smoothing, bloom, color temps, sharpen, blur.

That's what the Z buffer is for. ಠ_ಠ Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Posted May 8, 2020 1 hour ago, Franck said: You can have a triangle with a larger Z buffer than another triangle that pass over a lower Z buffer one. I don't quite understand what do you mean. The depth buffer has the same dimensions as the rendered image, there is a depth value for each pixel, but you don't even have to deal with it just enable GL_DEPTH_TEST and OpenGL will take care of it. When 2 triangle is on top of each other (or really close) that's can cause stitching, but it's more like a modelling issue. ಠ_ಠ Link to comment Share on other sites More sharing options...

Posted May 8, 2020 Author yeah ive already managed to get a model loaded and displayed with opengl no problems.
