The term texel has
arisen from the union of the concept in English "Texture
element" or "Texture pixel," and
basically, it is about the minimum unit of texture that is applied to a surface
of the digital image. Lifebloombeauty
Therefore we could
roughly say that in the case of a digital image, it is represented by a set of
pixels, while in the case of a texture, it is represented by a group of
texels. That is why this term is used almost exclusively for computer
graphics. Futuretechexpert
It should be noted that although
the texel can correspond to several pixels, it can also be less than one pixel, so
they are generally not visible to the human eye. Basically, a Texel is
simply one pixel within a texture image. Naturalbeautytrends
Typically, texels are mapped to
pixels to form the final image of a frame in which a texture has been embedded
into a 3D graphics surface, commonly referred to as texture mapping.
For all this, we can say that if
the images are represented by sets of pixels, then we can also point out that the
textures are represented by sets of Texels. Techsmartinfo
When the procedure
known as mapping or texture mapping is carried out, that is to say,
that a surface or a 3D graphic is textured, what happens is that the
renderer assigns Texels to the appropriate pixels to be able to represent the
output image that will be possible visualize.
In addition, when a
texture is made, the so-called filtering is usually used, which is a method
that is applied to fill in the spaces that may become empty between the
textures that make up the texture, and in this way, the possibility
that edges appear that may be visible between the texel
On the other hand,
we must bear in mind that in the case of texels, an extremely important piece
of information is the fill rate, information that will tell us how many
texels can be processed per second, and in this way, we can know, for
example, the performance of the computer equipment that is used for this,
mainly from the graphics card.
Fill rate numbers
are usually expressed in megapixels/sec or megapixels/sec, and their main
function is ultimately to inform users of the number of finished pixels
that are written to the frame buffer. Smarttechpros
Of course, the megapixels
are usually employed in creating 3D graphics, mainly from the latest video
games, where even today, we find the use of multiple layers of effects of
multiple textures.
The lighting, the
shadows, the textures, in short, all these elements that are part of modern
video games and that perhaps we do not pay adequate attention to, are
created from a set of texts that are part of the texture space that
will give the possibility of visually expressing a graph.
