We have le following issue. A is correct, B is not. As you can see the plot contour (red arrows) is wrong. We are sure that all the numerical data are perfect. What else should we check in OpenGL settings?
We are using the code (down) below to prepare the texture.
Code :glBindTexture(GL_TEXTURE_1D, textureName); glTexImage1D(GL_TEXTURE_1D, 0, GL_RGB, data.Width, 0, GL_BGR, GL_UNSIGNED_BYTE, data.Scan0); glTexParameteri(GL_TEXTURE_1D, GL_TEXTURE_MAG_FILTER, gl.NEAREST); glTexParameteri(GL_TEXTURE_1D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
