You can check the shape of crystals according to the type of igneous rock.

When you move the cursor inside the red rectangle on the right side, the crystal shape and color of the granite corresponding to the position are displayed.

To be precise, when you move your fingers to the left or right, the color is randomly scattered according to the ratio of ammonia mineral content below the fingers, and when you move your finger up and down, the size of the mineral changes according to the height of the mouse.

In addition, you can view the size and color of the crystals and try to match the name of the rock.

Explain to friends who want to know exactly what igneous rock is, that it is precisely when sorting igneous rocks while showing the illusion of igneous rocks in the middle, but eventually they are classified by the size of the color and the crystal.
