Seeing that it has entered the era of AR and VR, even playing games pays attention to three-dimensional interaction. If you paint, you will be proud to draw a 3D stereoscopic picture.

1. Materials and tools: paper, pencil, marker, marker and your hand.

2. First, press your hand on the paper and draw the outline of your hand with a pencil.

Please take out the marker at this time. The trick of drawing lines is to draw parallel straight lines outside the main body (here is the figure of the hand). And draw an upward curved arc where the hand is drawn to show the visual effect of the palm protruding picture. Circular arcs should be connected by straight lines. In addition, the radian of the finger part is greater than that of the palm part.

4. Draw a line on the basis of marker pen with colored pen, so that the 3D effect will be more obvious.

5, one color is not enough, you can add another color, and choosing a color with strong contrast will have a visual impact.

6. done.

Its principle is mainly to use the stereoscopic vision of human eyes. Because people's left and right eyes see things differently, we can use optical focusing. For example, if people put their hands on the desktop and their hands are protruding, then we can use the radian line that conforms to the protruding hands to express the three-dimensional effect, and the added colors can also show the shadow effect through certain contrast, thus increasing the three-dimensional effect of the picture.
