I'm currently working on importing a 3D model (obj file) using JavaFX.

first, i read the obj file and save its content in float arrays (vertices, normals, textures) and integer array for (faces).

for example:

In vertices the file contains:

v 3.227124 -0.065127 -1.000000

v 3.227124 -0.065127 1.000000

i save them in array like that: [3.227124,-0.065127,-1.000000,3.227124,-0.065127,1.000000].

and same for textures and normals.

while for faces: the file contains:

f 509/413/144 91/405/139 94/409/143

f 508/410/3 95/408/142 96/407/141

i save them in integer array as [509,413,144,91,405,139,94,409,143,508,410,3,95,408,142,96,407,141]

Now, i used javafx to draw the model using trianglemshes, but unfortunately the scene is empty and nothing is drawn.

would anybody help me to solve this problem and suggest for me a solution or links for a tutorial or a book.

This is the Code:
