Wood Texture Research 4--actual combat "Stump"

Now we have two textures on hand, one for the ring texture and the other for the bark texture. Now, we're going to use these two textures to make a stump.

The stump is actually a relatively simple object, basically it is a cylindrical body. Before we begin, we must first review the perspective method and the distribution of light and light in the cylinder. Figure one is a simple cylindrical model. As you can see, according to the perspective, the original circular cross-section is now oval, and the upper section of the Edge line radian is small, the bottom section of the Edge line radian is larger, which is also because of the perspective of the relationship. And the surface of the cylinder exhibits different reflective qualities in our hypothetical light from the left side, thus also visually caused the surface of the feeling, analysis of this reflection law, from left to right in turn can be divided into the surface of the cylinder of high light area, the junction line and reflection zone.

Okay, now we're going to start making stumps, and first we need to build a cylinder like the one on the diagram.

1. Create a new 500x500pixel,72dpi file. Create a new layer named surface, and use the rectangular selection tool to pull out a rectangular selection of approximately 240x280 size, saving the selection (Select->save SELECTION)

2. Then use the Circle selection tool to pull a rectangular selection with a size of 240x35 on top of the rectangle selection. Be sure to align this selection with the rectangular selection above it, and if necessary, pull some help lines first. Saves the selection to a new channel.

3. Then use the Circle selection tool to pull out a rectangular selection of size 240x75 below the rectangle selection, and align it with the rectangular selection above, saving the selection to the new channel.

4. When confirming the activation of the third selection, select->load SELECTION, select the channel to save the first selection, which is the rectangular selection, and select Add to SELECTION within the operation entry to merge the two selections.

5. Press the shortcut key D to set the color board to the default value, and then press the shortcut key g to select the Gradient tool, in the option panel press "EDIT" key to set the gradient parameters, please refer to figure two, in short, the three reflective areas mentioned above is achieved through the settings here.

6. Hold down the SHIFT key, from the selection of the most left has been pulling a gradient to the right end, three reflective areas formed.

7. Create a new layer named "section", select Menu Select->load SELECTION, call the second selection, Operation=new SELECTION.

8. Select Menu Edit->fill and fill the selection with 50%grey. Our cylinder is finished, how is it realistic? Now we're going to paste the texture we made onto this cylindrical body.

9. Copy the texture of the bark to a new layer called "bark" and place the layer above the "surface" layer, hold down the CTRL key, click the "surface" layer in the layer panel to call this layer's selection and select the menu Select->inverse the selection.

10. Confirm "Bark" as the current layer, press Del to remove excess texture. 11. Turn the pattern of the "bark" layer into hardlight mode.

12. The tree-ring texture is copied to the new layer named "Ring".

Figure Three

13. Because we do the ring texture is a positive circle, so it is very good to do, press the shortcut key ctrl+t into the free deformation mode, using scale and distort items to adjust the texture and the "section" layer shape the same oval, finished to delete the "section" layer.

14. Merge all the visible layers, our stumps are complete, and the final results are shown in Figure three.
