Given the statement: hl {font-family: Tahoma;}, which is referred to as the selector? O a. {font-family: Tahoma;} O b. Tahoma O c. font-family O d. hl

Skybox class (M Visual Studios): Modify the skybox class appropriately to handle cube mapping. This involves loading six images for the cube map, setting appropriate texture parameters, and ensuring the normals of the cube model that encoded and runs sucessfully Task: The upload_CubeMap_images() function in the Skybox.cpp file needs to be implemented sucessfully according to the instructions.Instructions: Enable cube mapping: Use glEnable(GL_TEXTURE_CUBE_MAP) to enable cube mapping. Generate a texture ID: Use glGenTextures() to generate a texture ID to hold the cube map. This ID is stored in the tex_buffer_ID member variable of the Skybox class. Bind the texture ID: Use glBindTexture() to bind the texture ID as the current buffer. Make sure to bind it as a cube map using GL_TEXTURE_CUBE_MAP. Load six images: Load all six images into the correct "place" in the cube map. You can use the provided file paths (BMP_NEG_X_FILE_PATH, BMP_NEG_Y_FILE_PATH, etc.) to load the images. (Make sure to…
