 A `.texture` file contains `4 * texture_width * texture_height` floating point values. Each group of four is to be interpreted as the RGBA values of a single texel.
 Successive values are delimited with a single space. After each `4 * texture_width` values, a newline is expected.

+Texture uploading is done via the following call:
+```c++
+glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA32F, texture_width, texture_height, 0, GL_RGBA, GL_FLOAT, data_target.data());
+```
+
+One peculiarity to be aware of is the use of different axis conventions. 
 Images typically have the origin in the lower left corner with y-axis pointing upwards, while OpenGL has the origin in the top left corner with the y-axis pointing **downwards**. 
 This means that the first four floats in the file describe the top left texel, and the first `4 * texture_width` values describe the top most row of texels.
-This is only important when using images that are asymmetric with respect to the horizontal. 
+This is only important when using damping textures that are asymmetric with respect to the horizontal. 
 If it is a problem, consider either flipping the image, or look into calling `stbi_set_flip_vertically_on_load(true)`. This can also be taken care of shader side.
