So … Let me continue the article about creation 3d street painting, first part starts from here: 3d street painting for dummies or how to do 3d anamorphic painting? 3d street painting or anamorphic painting can be made by any kind of material: by chalk or paint (acrylic or gouache) it’s up to you.
- In a previous post, we have made a grid in a promising reduction on the plane, according to the selected parameters sizes of grid squares 1,5×1,5 ft (AB segment length). The height of the human figure on the picture and the height of the beholder, who is standing on the main viewpoint is 5,5 ft., Distance to the viewpoint, 6 ft. As you can see in the photo below, placing our “apple sketch” on the grid we got,our 3d anamorphic painting on the site should look exactly the same as in our sketch, i.e. without distortion and deformation.
- Now we need to draw a grid without distortion, this is our projection sketch, with which we will work on the site and transfer the image onto the pavement.We are making our grid at the edge of the picture plane, which is our line H, the grid will be parallel to the picture plane and perpendicular to the plane of the base, i.e. the “asphalt”. The size of the grid squares is the same, 1,5 ft, in the sketch of course you have it in your chosen scale.
- Next… keep your eyes on it … Let’s make a number of the squares. Draw beam, I called it “projection beam” from the viewpoint N, to the point of any intersection of our drawing with a grid that lies in the perspective, I chose the edge of a apple leaf – it’s on our grid lines in the perspective (square base C2 ). Crossing our grid that is parallel to us, the projection beam makes a point, which is the edge of our apple leaf.
In this artful way we find all crossing points on our grid. Points that falls to the axis line, you can count by proportional calculation.To achieve more accurate result in making details and lines of your 3d painting, you should set smaller cell pitch. After we found all points we connect them with a smooth line, like small kids in the kindergarten ;)… 3d painting in our projection sketch is done! Wow!
The same way you make your painting on the walls and ceilings. Thank you for reading this! Hope my article will help you, good luck!
P.S. And do not forget that the 3d street painting or sidewalk chalk, 3d drawings and etc. is primarily a picture that requires drawing and painting skills, possession of color and composition, otherwise, it may not turn out spectacular.
