The images you will be able to download after purchase are not watermarked. When importing these papers into a graphic file with lower DPI resolution in graphic editing software, you may need to set the size of the imported image in the editor to 3600x3600 px manually. PNG digital papers in the pack have 300 DPI resolution, optimized for printing. You can use the papers for creating greeting cards, wedding invitations, scrapbooking kits, planners and other printables, ad banners, business branding, patterned clipart, or any of your other creative projects. This pattern is perfect for any product aimed at butterfly lovers. Complex tessellation patterns stand out and attract attention. The pattern used is geometric butterfly tessellation pattern I designed myself. A large size color chart image is included with the pack for convenience. Image files in the pack are sorted by hue. All other colors use exact color codes of popular named colors. Each pattern color comes in three background color variations: white, gray, and black. This is a pack of 250 seamless digital paper backgrounds in both PNG and SVG formats.Įach paper uses a named solid color for pattern and a monochrome color for background. If (!) /*report triangle shader compile errors*/. If (!) /*report tessellated triangle shader compile errors*/. Piece of main function: TessTriangleRainbow tessTriRainbow it is identically the same as the tessellated one : Shape ( "shaders/tesselation/triangleRainbow.1.vs", "shaders/tesselation/triangleRainbow.1.fs") base Shape class builds the program from shaders Non tessellated triangle source, is almost identical to the tessellated one: GLfloat TriangleRainbow::points = identically the same as tessellated ones Vertex shader for non tessellated triangle: #version 430 coreįragment shader for non tessellated triangle: #version 430 core GlUseProgram(*this) //the inherited overloaded (int) operator returns the program id GlVertexAttribPointer(1, 3, GL_FLOAT, GL_FALSE, 6 * sizeof(float), (void*)(3 * sizeof(float))) GlVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 6 * sizeof(float), (void*)0) get XYZ values into location 0 on vertex shader GlBufferData(GL_ARRAY_BUFFER, sizeof(points), &points, GL_STATIC_DRAW) "shaders/tesselation/triangleRainbow.vs", "shaders/tesselation/triangleRainbow.fs") : Tess ("shaders/tesselation/triangleRainbow.tcs", "shaders/tesselation/triangleRainbow.tes", TessTriangleRainbow::TessTriangleRainbow() It is responsible for compiling linking the shaders The base class Tess is tesselation shader aware Tessellated triangle source: GLfloat TessTriangleRainbow::points = Layout (triangles, equal_spacing, cw) in įragment shader for tessellated triangle: #version 430 core Tesselation evaluation shader: #version 430 core Tessellation control shader: #version 430 core Vertex shader for tessellated triangle: #version 430 core Note, exactly the same code and data but not tessellated looks ok: No matter that I do, the first ad second color is ignored: Only the last, third color is taken from the triangle data passed to shaders, see the TessTriangleRainbow::points in the C++ code snippet for tessellated triangle. So far consulting also these sources, but did not find the problem in my code yet: Īs failing to pass for complex shapes, I narrowed problem down to simple basic triangle. Passing data through tessellation shaders to the fragment shader Like I found here, the most consistent answer: Trying to pass the colour via tesselation shaders.
