I have set up a simple ray tracing in C++. I wanted to add the texture mapping to the sphere. It basically just map the texture from a PPM file to the sphere. Below are my code for the part. //Call shaderay from trace ray function // index_of_winning_object = index of scene object array // point = intersection point Color shadeRay (int index_of ...

If there exists any intersection, compute the point intersected on the sphere, which is a 3D coordinate, and texture map an Earth image to the sphere by using the algorithms of Parametric Texture Mapping. Diffuse Shading and Specular Shading were also computed in the results. The first problem is combining an image of earth and cloud.
Ray Tracing: Texture Mapping
https://ray-tracing-conept.blogspot.com/2015/01/texture-mapping.html
The easiest way to texture map onto a sphere is by defining v to be the latitude of the point and u to be the longitude of the point on the sphere. This way, the texture image will be "wrapped" around the sphere, much as a rectangular world map is wrapped around a globe. Figure 8. Mapping a rectangular world map onto a globe Figure 9.

there is a "perfect" mapping method that involves converting the position on the sphere to spherical coordinates and sampling your texture this way, but it is rather compute-intensive (a couple inverse trigonometric functions, so quite undesirable) and from your description my guess is you are using the tangent/bitangent/normal technique to …

The equation for a sphere is: x 2 + y 2 + z 2 = R 2 Where x, y and z are the coordinates of a cartesian point and R is the radius of a sphere centred at the origin (will see later how to change the equation so that it works with spheres which are not centred at the origin). It says that there is a set of points for which the above equation is true.
