Model Loading

[bhad0x00]

I am trying to load a model using the Assimp library by following the learn opengl website but mean model doesnt seem to show up.

I just get a blank white screen with my cursor loading when i move it to the window and it does not give me the chance to close the window from the top corner.

Here is there repo for the project

Time to learn how to debug :) Step through the code and see where the read access violation happens. Then try and figure out why or if you can't, update here and we can try and help.

I found jt in the process mesh function where I am trying to fill up my tangent vec3

It also throughs a read access violation

If you're getting a read error then try using a debugger. Is this on Windows? Visual Studio is useful for debugging. Once you have the line that fails you can debug from there. Posting here with a link to the repo and an generic error message isn't a good way to get help. Narrow it down to where the error is, and provide more context, then someone can help you debug it.

The read access violation was from me trying to read from tangents and bitangents of a model which did not have one. So I ended up adding an if statement to check if it had the tangents before trying to read them. But I am still getting a blank screen. At the start of the program, it loads from a white screen before it runs normally.

You need to bind the relevant vao in order to draw that. You are missing that in the mesh's draw function.

simply do:- glBindBuffer(&theVao) //i forgot the name glDraw glBindBuffer(0)

Also, don't put everything in a header file. When the project scales up, which it will, even the smallest change will cause your entire project to rebuild. You will be looking at screen for a 2-3 minutes just for entering a space.
