This consisted of a very complicated procedure that made furniture and objects embellished with decorations under tens and tens of layers of very shiny lacquer. The history of modern découpage has however beginning with the passion that the European courts showed towards a particular technique, arrived from Chinaalready in the 16th century and which was established in Europe especially at the end of the seventeenth century: lacquering. The first traces of this technique in Europe since the Middle Ages, when the scribal monks enriched their manuscripts in this way. In the 17th century, Italy, especially Venice, was at the forefront of trade with the Far East and it is generally thought that it is through these trade links that the cut out paper decorations made their way into Europe. From Siberia, the practice came to China, and by the 12th century, cut out paper was being used to decorate lanterns, windows, boxes and other objects. Nomadic tribes used cut out felts to decorate the tombs of their deceased. The origin of decoupage is thought to be East Siberian tomb art. The word decoupage comes from Middle French “decouper”, meaning to cut out or cut from something.
VOLUMETRIX DECOUPAGES SERIES
In pyramid decoupage, a series of identical images are cut into progressively smaller, identical shapes which are layered and fixed with adhesive foam spacers to create a 3D “pyramid” effect. Pyramid decoupage (also called pyramage) is a process similar to 3D decoupage. The variety of papers, glues, brushes, objects and scrap-art is so vast that even a beginner can approach this technique and produce impressive decorations.ģD decoupage (sometimes also referred to simply as decoupage) is the art of creating a 3D image by cutting out elements of varying sizes from a series of identical images and layering them on top of each other, usually with adhesive foam spacers between each layer to give the image more depth.
VOLUMETRIX DECOUPAGES PROFESSIONAL
Simple technique that does not require particular artistic skills is widespread today, with a great flourishing of magazines and specialized fairs and professional materials. The traditional technique used 30 to 40 layers of varnish which were then sanded to a polished finish.ĭécoupage Known in Italy as “poor lacquer” or “poor art”, it was introduced in the eighteenth century by Venetian furniture makers to shorten the time of realization of lacquered furniture in chinoiserie or with gallant scenes typical of the eighteenth century gluing cropped and painted molds great producer in the card industry was the Remondini printing press in Bassano del Grappa. Each layer is sealed with varnishes (often multiple coats) until the “stuck on” appearance disappears and the result looks like painting or inlay work. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from purpose-manufactured papers. Draw the quad, with the volume texture.Decoupage is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf and other decorative elements. if( SUCCEEDED( d3dDevice->BeginScene() ) )
VOLUMETRIX DECOUPAGES CODE
The code example below shows the entire rendering process for a strip of triangles. LPDIRECT3DVOLUMETEXTURE9 pVolumeTexture ĭ3dDevice->CreateVolumeTexture( 8, 4, 4, 1, 0, D3DFMT_R8G8B8,D3DPOOL_MANAGED,īefore rendering the primitive, set the current texture to the volume texture created above. The next step is to use the IDirect3DDevice9::CreateVolumeTexture method to create a volume texture, as shown in this code example. Now, create a vertex buffer and fill it with data from the vertices. #define D3DFVF_VOLUMEVERTEX (D3DFVF_XYZ|D3DFVF_DIFFUSE| The code examples below show the steps required to use a volume texture.įirst, specify a custom vertex type that has three texture coordinates for each vertex, as shown in this code example. The following diagram shows what a volume texture with multiple levels looks like. Volumes can have subsequent levels in which the dimensions of each level are truncated to half the dimensions of the previous level. Volumes are organized into slices and can be thought of as width x height 2D surfaces stacked to make a width x height x depth volume. You can use volume textures for special effects such as patchy fog, explosions, and so on. Volumes are not rendered directly because there are no three-dimensional primitives that can be painted with them. As the primitive is drawn, each contained pixel is filled with the color value from some pixel within the volume, in accordance with rules analogous to the two-dimensional texture case. Three-element texture coordinates are required for each vertex of a primitive that is to be textured with a volume. Volume textures are three-dimensional collections of pixels (texels) that can be used to paint a two-dimensional primitive such as a triangle or a line.
