3D Art Forms Description Three-dimensional art forms can be created according to the same principles as two-dimensional slate forms.Features of the espalier form:slate form is derived from a three-dimensional geometric shape fruitwood is grown short on the stem branch3D art forms are often a showpiece in your garden. Opinion 3D espalier shapes are ideally suited as a solitary tree, as a focal point in the garden.ExposureMake sure that all framework branches are well exposed to the sun:Use these espalier forms as a solitary or as full wind guidance, but not along a fruit wall.If you plant a row of these espalier forms, use a north-south planting direction.Lead constructionIn general, the following applies:For a solitary tree, use a self-supporting metal structure that is firmly anchored in the ground.Use a tension wire construction for a row of trees.The slate construction is sometimes temporary, sometimes (semi-)permanent in nature. Main types The espalier forms are classified according to their basic mathematical shape. Beam shapesStandard shapes with the contours of a beam. Pyramid shapesStandard shapes with the contours of a pyramid. Cylinder shapesStandard shapes with the contours of a tube. Sphere shapesStandard shapes with the contours of a sphere. Arch shapesStandard shapes with the contours of a tunnel.
