high and low meshes (i used low meshes of course) high low

and my opengl screen:

That's not how bump mapping works. Bump mapping adds additional detail to a model, but doesn't change the triangles. You need to render a mooth mesh to make the edges invisible (the normals of a vertex shared by 2 triangles must be the same)

  • \$\begingroup\$ so i did right ? but this video seems perfect with not smooth low mesh youtu.be/ApzVWuPa4A4?t=1113 \$\endgroup\$ – Emre Kaya Mar 27 '18 at 6:46
  • \$\begingroup\$ @EmreKaya your model is showing flat shading, you might want to adjust the the normals. Notice how the faces all show rigid along the edges? \$\endgroup\$ – Sidar Mar 28 '18 at 14:48
