MIP Filter
| Field | Description | Preview |
|---|---|---|
| Box | Simplest MIP-map generation algorithm. However, the box filter has a number of limitations that can be quite noticeable with certain textures. For example, if a texture contains very narrow features (e.g., lines), then aliasing artifacts may be very pronounced | |
| Cubic | Generation with weighted sum of eight pixels. The advantage of the cubic filter over the box is that it can have negative side lobes (weights) which help maintain sharpness while reducing the image. This can help reduce some of the blurring effect of filtering with mipmaps | |
| Point | (aka Nearest-neighbor interpolation) Uses only one pixel from the mipmap This is a simple and fast texture filtering method that works well in some cases, but can create visual artifacts and reduce image quality in more complex scenes. | |
| Triangle | ||
| Quadratic | This method offers a balance between quality and performance It uses an interpolation method that is based on quadratic equations. Instead of just selecting one pixel (as in Point), this method considers three pixels - one from the selected mipmap level and the two closest to it - to greatly improve the smoothness of the transition of color values. | |

Different shading algorithms
| Field | Description |
|---|---|
| OrenNayar Blin | Oren-Nayar shading is a lighting model used in computer graphics to render matte (rough) surfaces with respect to their micro geometry. Blin shading uses a combination of diffuse and specular light reflection to achieve a more realistic image of shiny objects. |
| Blin Phong | Blin shading uses a combination of diffuse and specular light reflection to achieve a more realistic image of shiny objects. Phong shading model can achieve good visual results, making objects appear more three-dimensional and realistic, but at the same time it cannot always accurately reproduce lighting effects on more complex or uneven surfaces. |
| Phong Metal | Phong shading model can achieve good visual results, making objects appear more three-dimensional and realistic, but at the same time it cannot always accurately reproduce lighting effects on more complex or uneven surfaces. Metal shading is focuses on the realization of materials imitating metallic surfaces. |
| Metal OrenNayar | Metal shading is focuses on the realization of materials imitating metallic surfaces. Oren-Nayar shading is a lighting model used in computer graphics to render matte (rough) surfaces with respect to their micro geometry. |
