I am trying to Polymorphism in c++ but when I try to call a function , the _vfptr is equal to 0xcccccccccccccccc .

Here is the Object class who contain virtals functions :

I try to load the FBX model in the last contains of this learnopengl tutorial, but I only can load diffuse texture of the FBX. I had tried the solution of adjusting the order of layout in vertex shader, but it didn't work. The result of material->GetTextureCount(type) is 0 when type isn't aiTextureType_DIFFUSE. Here is my code:

mesh.h

Let's say that I have my geometry and created an index buffer containing the triangle adjacency information. Then, changed the draw mode from GL_TRIANGLES to GL_TRIANGLE_ADJACENCY. The question is, can I convert the geometry from triangle adjacency to triangles strip using the geometry shader?

something like this:

I am trying to combine 2 programs

1. One is an empty room with a table and 2 chairs

1. The other draws a mesh of a Taurus

I have combined both and this was the result I got

Some of the surfaces of the table and chairs have disappeared. Can someone tell me why? I have already made an additional VBO and VAO to hold the vertice data of the meshes. However it seems to be affecting the surfaces of the cubes.

Here is my program

I am trying to load 2 different meshes (a taurus and a monkey head) in my program. Both using the same load_mesh function.

I used load_mesh for the taurus in the init function. The vertice data for this mesh was stored in g_pMeshVertices. It looked like this.

Then I loaded a second one and it looked like this (below). The second mesh (monkey head) successfully appeared but half of the previous mesh disappeared. What I did was I used the load_mesh function again but for the "monkey head" inside init. The vertices for the new mesh was also stored in g_pMeshVertices. However, I created a new VBO and VAO to store the new vertices of g_pMeshVertices but it seems to be affecting my previous mesh. Can someone tell me why?

Here is my code

I'm trying to combine the versatility of Open Asset Import Library (reading in a variety of 3D model filetypes) with NVidia Optix ray tracing to render the models.

So far, it is working whenever the model I'm rendering is made up of a single mesh. When I try to render a file with more than one mesh, I get only partial results. I can't narrow down where the issue is, looking for some insight. Relevant code here:

Loading a file using assimp importer and creating the optix buffers:

I'm trying to load a mesh into my directx app. I can successfully load any mesh but texture coordinates are wrong on a side of mesh. (Only a side. The other side's texture is mapped correctly) ScreenShot

Here's my code.

Model.h

I have a program I use for test-loading models into OpenGL in C. The code for this is pretty straightforward as far as model loading with Assimp goes (to my understanding):
