<div>Texture metadata (addressing, filtering, wrapping,
blending...) is supported by both OpenGL and D3D in a similar
enough way that makes a uniform API possible and not
convoluted. This metadata can be added to Texture, or perhaps
better, TextureMap.</div>
<div>Unfortunately, there is no ideal way of creating the public
API because the textures in PhongMaterial are represented as
Images. Interestingly, there are comments on the map
properties in PhongMaterial that touch on this, "// TODO: 3D -
Texture or Image? For Media it might be better to have it as a
Texture", but I think that the question didn't get resolved in
time and Image stayed.</div>
<div><br>
</div>
<div>Because we can't change the type, we have the following
options:</div>
<div>1. Duplicate the methods in PhongMaterial that use
ObjectProperty<Image> and have a set that uses
ObjectProperty<Texture> (or TextureMap) with it taking
precedence. I think that this is a bad option as it creates
API noise and is confusing to use.</div>
<div>2. Add the metadata to Image and enhance its public API. I
don't think that this is a good option either because it will
bloat Image with specific data that is not widely used.</div>
</div>
</blockquote>
<p>Could you subclass Image? I'm not that well versed with Textures
in modern gfx systems, but I do know that a texture is often just
a tileable image, so subclassing image seems to be an option. In
other words, if a Texture always satisfies "is-an-image", a
subclass seems reasonable.<br>
</p>
<p>Alternatively, perhaps Image and Texture could implement some
interface, and the currently public API could change to that
interface type.<br>

<blockquote type="cite">
<div dir="ltr">
<div>3. Create a new Material, placeholder name PhongMaterial2,
that uses textures instead. We might want to look at other
breaking enhancements for PhongMaterial so we can plan ahead
better this time. I think that this is a reasonable option
whose eligibility depends on how much we can't update the
current PhongMaterial. Mipmaping, which requires a set of
images, might be one of them.</div>
</div>
</blockquote>
<p>Are mipmapped textures commonly provided as multiple images, or
are the smaller images just scaled down versions that could be
(pre)calculated from the main texture image?</p>
<p>Another option may again be to subclass Image, as a mipmapped
texture is mostly just scaled versions of the same image,
providing the highest quality image for the normal Image API would
be fine, and having extra API in the subclass to get access to
pre-scaled mip mapped versions is not unreasonable.<br>
</p>
<blockquote type="cite">
<div dir="ltr">
<div>4. Create a separate set of methods inside PhongMaterial
that deal with the texture metadata only. These will be
something like `ObjectProperty<TextureData>
diffuseTextureDataProperty()` and similarly for the other
maps. I think that this option is also reasonable, although it
also creates API noise (these only take effect if the maps are
used to begin with).</div>
<div><br>
</div>
<div>I didn't look deeply into texture aspects outside of the
discussed filtering, but I think we should take the
opportunity to do so. For filtering, I have the following
ideas:</div>
<div><br>
</div>
<div>For min/mag filters: an enum with NEAREST
(nearest-point/neighbor sampling) and LINEAR ((bi)linear
sampling).<br>
</div>
<div>For mipmap filters: an enum with NEAREST (nearest mipmap
level) and LINEAR (linear interpolation between levels). While
some APIs have a NONE mode to disable mipmaping, the
inexistence of mipmaps can be used as a disabled mode.</div>
<div>Even though they use the same constant names, the meaning
is different, so I think the enums should be separate.</div>
<div><br>
</div>
<div>For mipmaps: a List<Image>. Autogeneration of mipmaps
can also be considered.</div>
<div><br>
</div>
<div>Anisotropy is supported in D3D via a filter type
(ANISOTROPIC) plus a strength factor, and in OpenGL since
version 4.6 (which version does JavaFX use?). Metal and Vulkan
just use a strength factor to turn it on regardless of the
filter. I think that this is a more flexible approach and we
could add a single int/double property to control anisotropy.</div>

question to answer is whether the filtering
method is applied to all maps/textures of the

the former makes more sense. If that's the case,
the texture filtering parameter will be just one

We could round

think that if

a union of the

if a few are

only one of

similar to a
conditional
